This reaction is an example of β -elimination.
Hydrogen is removed from β -carbon and halogen from α -carbon, hence, dehydrohalgoenation reaction.
Generally in E2 reaction Zaitsev alkene is formed as major product (more stable alkene).
Elimination reaction of 2-Bromo-pentane to form pent-2-ene is
(a) β-Elimination reaction
(b) Follows Zaitsev rule
(c) Dehydrohalogenation reaction
(d) Dehydration reaction
