Question

(e) Which of the following represent the name and formula of 2nd member of homologous series
having general formula Cn H2n+2?
(i) Metham, CH4
GD) Ethane, C2H6
(ii) Ethene, C2H4
(iv) Ethyne, C2H2​

Answer 1

Answer:

(ii) Ethane C₂H₆

Explanation:

General Formula Given = CnH(₂n+₂)

To find the second member of such homologous series :-

• Placing 2 in place of n.

=> C₂H₍₂ ₓ ₂ ₊ ₂₎

=> C₂H₆

That is (ii) Ethane C₂H₆
