QQuestion
Which of the following options has all the compounds which are members of the same homologous series?
(a) CH4, C2H6, C3H8
(b) CH4, C2H6, C3H6
(c) C3H4, C3H6, C3H8
(d) C2H4, C3H6, C4H10
✓Answer
(a) CH4, C2H6, C3H8
Explanation:
These three molecules are consecutive members of the alkane series, which has the general formula CnH2n+2. Each successive member differs from the previous one by a CH2 group, satisfying the defining characteristic of a homologous series.
