Answer
(a) A homologous series is a group of organic compounds having a similar structure and similar chemical properties in which the successive compounds differ by a CH2 group.
(b) The difference in the molecular formula of two adjacent homologues:
- In terms of molecular mass is 14 a.m.u.
- In terms of number & kind of atoms per molecule is that each member of the series differs from the preceding one by the addition of CH2 group.
