Question
Chemistry Question on Alcohols, Phenols and Ethers
The relative ease of dehydration of alcohol is
A
1� = 2� = 3� alcohol
B
3� < 2� <1� alcohol
C
3� > 2� > 1� alcohol
D
none of these.
Answer
3� > 2� > 1� alcohol
Explanation
Solution
Since dehydration of alcohols to alkenes occurs through the carbocation formation and the stability of carbocations follows the order : 3� > 2� > 1� Therefore, the ease of dehydration of alcohols follows the order : 3� alcohols > 2� alcohols > 1� alcohols
