Solution
When 1,1-dichlorobutane is treated with sodaamide, it undergoes dehydrochlorination to form 1-butyne.CH3CH2CH2CHCl2+NaNH2/NH3dehydrochlorination−−−−−−−−−−−−→CH3CH2C≡CHSoda amide abstracts an acidic hydrogen atom from 1−butyne.
This is followed by a nucleophilic attack on 1−bromoethane to form 3−hexyne.CH3CH2−C≡C−H+NaNH2→CH3CH2−C≡C−1−bromoethane−−−−−−−−−→−HBrCH3CH2C≡CCH2CH3
Hence, the correct answer is 1.
CH3CH2CH2CHCl2+NaNH2/NH3dehydrochlorination−−−−−−−−−−−−→CH3CH2C≡CH
Soda amide abstracts an acidic hydrogen atom from 1−butyne.
This is followed by a nucleophilic attack on 1−bromoethane to form 3−hexyne.
This is followed by a nucleophilic attack on 1−bromoethane to form 3−hexyne.
CH3CH2−C≡C−H+NaNH2→CH3CH2−C≡C−1−bromoethane−−−−−−−−−→−HBrCH3CH2C≡CCH2CH3
Hence, the correct answer is 1.
