Question

write tje mext homologue of each of the following: C2H4,C4H6

Answer 1

C2H4 is seturated
Name of C2H4 is ethene

Answer 2

C2H4 :

The next homologue will be C3H6.

Reason: As it is in form of CnH2n.

C4H6 :

Here it will be C5H8.

Reason: It is in form of CnH2n-2.

So the simple logic is to find the relationship between the subscript of carbon and hydrogen and then increase the value of n( subscript of carbon) by 1 to get the homologue series.
