Elimination reaction of 2-Bromo-pentane to form pent-2-ene is:

1. β-Elimination reaction
2. Follows Zaitsev rule
3. Dehydrohalogenation reaction
4. Dehydration reaction

Correct answer: Follows Zaitsev rule

Solution

The elimination reaction of 2-Bromo-pentane to form pent-2-ene is a β-elimination reaction, follows Zaitsev's rule (major product is the more substituted alkene), and is a dehydrohalogenation reaction. However, it is not a dehydration reaction as no water is removed.
