Question

which of these undergo substitution reaction C2 H6 or C2 H4 ?why?​

Answer 1

Explanation:

C2H6 is CH3CH3 (Ethane molecule). It is a saturated compound having no carbon-carbon multiple bond(s). Hydrogenation, i.e. addition of hydrogen can't take place because it requires carbon carbon double/triple bond.

However C2H4 (Ethene) is CH2=CH2 having one carbon-carbon double bond. It can undergo hydrogen addition at the double bond to form CH3-CH3.
