What is a homologous series?
Write the molecular formula of first two members of homologous series having functional group – OH
Define a homologous series. Give the name and structural formula of one homologue of the following:
CH3OH
An organic compound having the molecular formula C3H6O can exist in the form of two isomers A and B having different functional groups. The isomer A is a liquid which is used as a solvent for nail polish. The isomer B is also a liquid. An aqueous solution of one of the lower homologues of B is used for preserving biological specimens in the laboratory
(a) What is compound A?
(b) Write the electron-dot structure of A.
(c) What is compound B?
(d) Write the electron-dot structure of B.
(e) Name the lower homologue of compound B which is used in preserving biological specimens.

Give three points to differentiate between saturated and unsaturated
hydrocarbons.
Two statements are given - one labeled Assertion (A) and the other labeled Reason (R).
Assertion (A): In a homologous series of alcohols, the formula for the second member is C2H5OH and the third member is C3H7OH.
Reason (R): The difference between the molecular masses of the two consecutive members of a homologous series is 144.
The phenomenon in which compounds having different structural formulae have the same molecular formula is called _______.
Saturated hydrocarbon : Single bond : : Unsaturated hydrocarbon : _______
