Chapter 10 - Haloalkanes and Haloarenes Haloalkanes: Chapter 11 - Alcohols, Phenols and Ethers Alcohols: Chapter 13 - Amines Amines: Nucleic Acids: Chapter 15 - Polymers Classification - natural and synthetic, methods of polymerization addition and condensation , copolymerization, some important polymers: They are placed in between s- block and p-block elements.

They show a regular transition from the highly electropositive metals of s- block elements to the less electropositive p-block elements.

So they are called transition elements.

Class 12 Chemistry Chapter 9. A salt that keeps its identity only in solid state is called a double salt. In solution they dissociate into component ions.

NH4 2SO4. Al2 SO4 3. The salt that keeps its identity both in solid and solution states is called a complex salt. Class 12 Chemistry Chapter These are compounds containing halogen atoms attached to an alkyl or aryl group.

These are compounds containing C — O single bond. The functional group present in Alcohols and phenols is — OH hydroxyl group and that present in ethers is —O — group oxy group.

In alcohols, the —OH group is bonded to an alkyl group. So the general formula of alcohols is R-OH. But in phenols, the —OH group is bonded to an aryl group.

So the general formula of phenols is Ar-OH. In aldehydes, the carbonyl group is bonded to a carbon and hydrogen while in ketones, it is bonded to two carbon atoms. The carbonyl compounds in which carbonyl group is bonded to oxygen are known as carboxylic acids, and their derivatives e. Amines are the derivatives of ammonia.

Chemistry Notes Class XII

Like ammonia, the nitrogen atom in amines is also sp3 hybridised with an unpaired electron in one of the sp3 hybridised orbitals. So the shape of amines is also pyramidal.

The molecules present in living system like carbohydrates, proteins, nucleic acids, lipids, vitamins etc. Polymers are very large molecules having high molar mass and are formed by the combination of a large number of simple molecules called monomers. The process of formation of polymers from respective monomers is called polymerisation. Polymers are also called macromolecules.
