(a) -Elimination reaction
(b) Follows Zaitsev rule
(c) Dehydrohalogenation reaction
(d) Dehydration reaction
(a) -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 -elimination.
- Hydrogen is removed from -carbon and halogen from -carbon, hence, dehydrohalgoenation reaction.
- Generally in reaction Zaitsev alkene is formed as major product (more stable alkene).
