The relative ease of dehydration of alcohols follows following order `:`

A

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

B

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

C

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

D

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

Text Solution

Verified by Experts

The correct Answer is:
B
Dehydration of alcohols involve the formation of carbocation intermediates. More the stability of carbocation, more will be ease of alcohol towards dehydration.
`because` The order of stability of carbocation is
`3^(@) gt 2^(@) gt 1^(@)`
`therefore ` The order of ease of dehydration of alcohol is
`3^(@) gt 2^(@) gt 1^(@)`
