Question

Write the next homologue of each of the following:
(i) C2H4
(ii) C4H6

Answer 1

Answer:

1. C3H6

2. C5H8

Answer 2

i) C3H6 (propane)

ii) C5H8 (Isoprene)

Explanation:

A homologous series is a series of compounds that have the same functional group. This gives them similar chemical and physical properties. Example: Alkanes, carbohydrates, alkenes. Adjacent members in a homologous series are called adjacent homologues.

The series mentioned in the question is a homologous series with the function unit CH2.

1. So the next homologue of C2H4 is C3H6 (propane).
2. The next homologue of C4H6 is C5H8 (Isoprene).
