Elimination reaction of 2-Bromo-pentane to form pent-2-ene is                                  [NEET 2020]

[a] \[\beta \]-Elimination reaction

[b] Follows Zaitsev rule

[c] Dehydrohalogenation reaction

[d] Dehydration reaction

A) [a], [c], [d], [b]

B) [b], [c], [d], [a]

C) [a], [b], [d], [c]

D) [a], [b], [c], [d]

Correct Answer: D

Solution :

[d]

Since \[\beta \]-hydrogen is abstracted it is \[\beta \]-elimination.

Since more substituted alkene is formed, it follows zaitsev's rule.

Since 'H' and 'Br' are removed, it is dehydro-halogenation.
