Question

The next homologue of Butane is

a) Hexane

b) Pentane

c) Ethane

d) Heptane​

Answer 1

Answer:

The molecular formula of ethane is C2 H6

. To get its fourth homologue, we have to add 4×CH2=C4H2 to it.

C2H6+C4H=C6H14

=C6H14 is the molecular formula of hexane.

Thus, hexane is the fourth homologue of ethane.
