Identify the major product of dehydrohalogenation of CH_3 - CH_2 - CH(Br) - CH_3

MHT CET 2026 Chemistry question

Identify the major product of dehydrohalogenation of \mathrm{CH_3-CH_2-CH(Br)-CH_3}

(A)\mathrm{CH_3-CH_2-CH=CH_2}
(B)Correct
(C)
(D)

Answer: (B)

Solution

The substrate is 2-bromobutane. Dehydrohalogenation (alcoholic KOH, -elimination) follows Saytzeff's rule: the more substituted, more stable alkene is the major product. Removing H from C-3 (more substituted -carbon)
