Q. 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), (c), (d)
B) (b), (c), (d)
C) (a), (b), (d)
D) (a), (b), (c)
Explanation
[Solution] Loss of HBr from 2-bromopentane is a $\beta$-elimination (dehydrohalogenation) following Zaitsev's rule; it is not a dehydration. Answer (4).
