The major product '\(\mathrm{X}\)' of the following reaction is
- A 3, 4-dimethylpent-1-ene
- B 3-methylpent-2-ene
- C 3, 3-dimethylpent-1-ene
- D 2, 3-dimethylpent-2-ene
Answer & Solution
Correct Answer
(D) 2, 3-dimethylpent-2-ene
Step-by-step Solution
Detailed explanation
The reaction is an acid-catalyzed dehydration of a secondary alcohol, 3,3-dimethylpentan-2-ol. The mechanism proceeds via the formation of a carbocation intermediate. Step 1: Protonation of the hydroxyl group by \(H_{2}SO_{4}\) to form a good leaving group, \(-OH_{2}^{+}\). Step…
