Question

How many statements are correct about the elimination reaction of 2-bromopentane to form pent-2-ene:
(A) $β$ -elimination reaction
(B) Follows zaitsev's rule
(C) Dehydrohalogenation reaction
(D) Dehydration reaction

Solution

$5 C H_{3} - 4 C H_{2} - 3 C H - 2 C | B r H - 1 C H_{3} β elimination - ------- \to - H B r 5 C H_{3} - 4 C H_{2} - 3 C H = 2 C H - 1 C H_{3}$

(A) $β -$ hydrogen is removed so it is a $β -$ elimination reaction.
(B) Major product is most substituted alkene which is formed by Zaitsev's rule.
(C) In this elimination rection hydrogen halide $(H B r)$ is getting removed, hence it is a dehydrohalogenation reaction.
