Rate of dehydration of alcohols follows the order

A

`2^(@) gt 1^(@) gt CH_(3)OH gt 3^(@)`

B

`3^(@) gt 2^(@) gt 1^(@) gt CH_(3)OH`

C

`2^(@) gt 3^(@) gt 1^(@) gt CH_(3)OH`

D

`CH_(3)OH gt 1^(@) gt 2^(@) gt 3^(@)`

Text Solution

Verified by Experts

The correct Answer is:
B
The order of dehydration among three type of alcohols is `3^(@) gt 2^(@) gt 1^(@) gt CH_(3)OH`. This behaviour is related to the relative stabilities of carbocations `(3^(@) gt 2^(@) gt 1^(@))`.
