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
Options
- A(a), (c), (d)
- B(b), (c), (d)
- C(a), (b), (d)
- D(a), (b), (c)
Correct answer
D. (a), (b), (c)
Step-by-step solution
This reaction is an example of β -elimination. Hydrogen is removed from β -carbon and halogen from α -carbon, hence, dehydrohalgoenation reaction. Generally in E 2 reaction Zaitsev alkene is formed as major product (more stable alkene).
