Question

Elimination reaction of 2-bromo-pentane to form pent-2-ene is:
(a) $\beta$-Elimination reaction
(b) Follows Zaitsev rule
(c) Dehydrohalogenation reaction
(d) Dehydration reaction

• A. (a), (b), (d)
• B. (a), (c), (d)
• C. (a), (b), (c)
• D. (b), (c), (d)

Answer 1

The correct option is C (a), (b), (c)


(a) $\beta -$hydrogen is removed so it is a $\beta -$ elimination reaction.
(b) Major product is most substituted alkene which is formed by Zaitsev's rule.
(c) In this elimination rection hydrogen halide $\left(HBr\right)$ is getting removed, hence it is a dehydrohalogenation reaction.
