Open in App
Solution
The correct option is C alkyne
Gem dihalides on treatment with alcoholic KOH undergo dehydrohalogenation. The reaction is as follows:
CH3−CHBr2alc.KOH−−−−−−→H−C≡C−H
1,1-dibromoethane acetylene
Preparation of alkyne by heating ethylidene bromide with alc. KOH followed by sodamide in ammonia solution.
