Summary of each chapter is followed by objective questions which are helpful to dig into the concepts. However, I might not suggest this book if u r looking for some serious theory on each chapter.
It covers every topic. It is self explanatory. Ansel back 23 Aug, As far as Flipkart is concerned: Great delivery by flipkart. Got it in within a week of ordering. Packaging was excellent. As far as the book is concerned: Book is very nice, with detailed theory and loads of example problems with solutions of each and every type. Perfect book for self study. Also has unsolved questions of both school level and JEE and other competition exams. Such questions also have answer answer hints.
I would recommend this book strictly for the board exams poi Pradeep textbook of chemistry that I bought had pages which easily came out pages when I tried to turn the pages. The binding wasn't proper. So do please think twice before purchasing this book from flipkart. Never expected this from flipkart.

Pradeep's New Course Chemistry Vol. I&II Class - 11 by S.C. Kheterpal Dr. S.N. Dhawan
Some Basic Principles pradeep chemistry class 11 e-books Techniques. Chemistry pradeep chemistry class 11 e-books called pradeep chemistry class 11 e-books science of atoms and molecule.
It is basically concerned with laws and theories of the different branches of chemistry. These properties can be classified into two categories — physical properties and chemical properties. P h ysical properties are those properties which can be measured or observed without changing the identity or the composition of the substance.
The measurement or observation of c hemical properties requires a chemical change occur. Burning of Mg-ribbon in air. C h e m ical properties are characteristic reactions of different substances; these include acidity or basicity, combustibility etc.
Many properties of matter such as length, area, volume, etc. M e t r ic System was based on the decimal system. The SI system has sevenbase units. M ass and Weight-- Mass of a substance is the amount of matter present in it while weight is the force exerted by gravity on an object. The mass of a substance is constant whereas its weight may vary from one place to another due to change in gravity.
The mass of a substance can be determined very accurately by using an analytical balance. Volume-- Volume has pradeep chemistry class 11 e-books units of length 3. A common unit, litre L is not an SI unit, is used for measurement of volume of liquids. Density of a substance is its amount of mass per unit volume.
Here, K is the SI unit. We can write Similarly, 0. P rec ision refers to the closeness of various measurements for the same quantity. Accuracy is the agreement of a particular value to the true value of the result. Treasure mp3 juices express it more accuratelywe express it with digits that are known with certainty. These are called as Significant figures. They contain all thecertain digits plus one doubtful neelakashamlo song doregama info in a number.
The decimal place does not determine the number of significant figures. For example, 2. For example, 0. For example, Zeros at the end of a number without decimal point are ambiguous. Pradeep chemistry class 11 e-books number of significant figures in this number is 2, while inAvogadro's number 6. The rounding off procedure is applied to retain the required number of significant figures. If the digit coming after the desired number of significant figures happens to be more than 5, the precedingsignificant figure is increased by one, 4.
If the digit involved is less than 5, it is neglected and the preceding significant figure remains unchanged, 4. If the digit happens to be 5, the last mentioned or preceding significant figure is increased by one only in case ithappens to be odd.
In case of even figure, the preceding digit remains unchanged. Dimensional Analysis During calculations generally there is a need to convert units from one system to other. This is called factor label method or unit factor method or dimensional analysis. For example- 5 feet and 2 inches height of an Indian female is to converted in SI unit. An element pradeep chemistry class 11 e-books the simplest form of matter that cannot be split into simpler substances or built from simpler substances by any ordinary chemical or physical method.
There are elements known to us, out of which 92 are naturally occurring while the rest have been prepared artificially. Elements are further classified into metals, non-metals and metalloids.
A compound is a pure substance made up of two or more elements combined in a definite proportion by mass, which could be split by suitable chemical methods. Inorganic compounds are those, which areobtained from non-living sources such as minerals. For example, common salt, marble and limestone. Organiccompounds are those, which occur in living sources such as plants and animals.
They all contain carbon. Pradeep chemistry class 11 e-books compounds are oils, wax, fats etc. A mixture is a combination of two or more elements or compounds in any proportion so that the components do not lose their pradeep chemistry class 11 e-books.
Air is an example of a mixture Mixtures are of two types, homogeneous and heterogeneous. The components of such mixtures cannot be seen under a powerful microscope. They are also called solutions. Examples of homogeneous mixtures are air, seawater, gasoline, brass etc. Given by Antoine Lavoisier in It states that matter mass can neither be created nor destroyed.
This law was proposed by Louis Proust inwhich states that: L aw of Multiple Proportions Proposed by Dalton inthis law states that: Given by Gay Lussac in According to this law when gases combine or are produced in a chemical reaction they do so in a simple ratio by volume provided all gases are at same temperature and pressure.
InGiven by Avogadro According to this law equal volumes of gases at the same temperature and pradeep chemistry class 11 e-books should contain equal number of molecules. Molecules are classified as homoatomic and heteroatomic. Homoatomic molecules are made up of the atoms of the same element and heteroatomic molecules are made up of the atoms of the different element have different atomicity number of atoms in a molecule of an element like monoatomic, diatomic, triatomic and polyatomic.
One atomic mass unit is defined as a mass exactly equal to one twelfth the mass of one carbon atom. Atomic mass of an element is defined as the average relative mass of an atom of an element as compared to the mass of an atom of carbon taken as Pradeep chemistry class 11 e-books quantity of an element whose mass in grams is numerically equal to its atomic mass.
In simple terms, atomic mass of an element pradeep chemistry class 11 e-books in grams is the gram atomic mass or gram atom. Molecular mass of a substance is defined as the average relative mass of its molecule as compared to the mass of an atom of C taken as Therefore the molecular mass of CO2 is 44 amu. It is obtained by adding the atomic masses of all the atoms present in one molecule. A quantity of substance whose mass in grams is numerically equal to its molecular mass is called gram molecular mass.
In simple terms, molecular mass of a substance expressed in grams is called gram molecular mass. Sum of atomic masses of the elements present in one formula unit of a compound. It is used for the ionic compounds. Mole is defined as the amount of a substance, which contains the same number of chemical units atoms, molecules, ions or electrons as there are atoms in exactly 12 grams of pure carbon A mole represents a collection of 6. T h e mass of one mole of a substance in grams is called its molar mass.
The volume occupied by one mole of any substance is called its molar volume. It is denoted by Vm. One mole of all gaseous substances at K and 1 atm pressure occupies a volume equal to The unit of molar volume is litre per mol or millilitre per mol. An empirical formula represents the simplest whole number ratio of various atoms present in a compound.
CH is the empirical formula of benzene. The molecular formula shows the exact number of different types of atoms present in a molecule of a compound. C6H6 is the molecular formula verdiana lontano dagli occhi benzene. Relationship between empirical and molecular formulae. Shorthand representation of a chemical change in terms ofsymbols and formulae of the substances involved in the reaction is called chemical equation.
The substances that react among themselves to bring about the chemical changes are known as reactants, whereas the substances that are produced as a result of the chemical change, are known as products.
L imiting Reagent- The reactant which gets consumed first or limits the amount of product formed is known as limiting reagent. Reactions in Solutions-- The concentration of a solution can be expressed in any of the following ways.
M ass Percent is the mass of the solute in grams per grams of the solution. Volume percent is the number of units of volume of the solute per units of the volume of solution. M o larity of the solution is defined as the number of moles of solute dissolved per american airlines arrival lounge cdg s dm 3 of the solution.
It isdenoted by the symbol M. Measurements in Molarity can change with the change in temperature because solutionsexpand or contract accordingly. In terms of weight, molarity of the substance can be expressed as: To calculate the volume of a definite solution required to prepare solution of other molarity, the following equation is used: Molality- Molality is defined as the number of moles of solute dissolved per g 1 kg of solvent.
Molality is expressed as 'm'. Mole Fraction is the ratio of number of moles of one component to the total number of moles solute and solvents present pradeep chemistry class 11 e-books the solution.
