Arrange the following alcohols in the decreasing order of
dehydration with conc. `H_(2)SO_(4)`.

A

`(ii)gt(iii)gt(iv)gt(i)`

B

`(i)gt(iv)gt(iii)gt(ii)`

C

`(iii)gt(ii)gt(iv)gt(i)`

D

`(i)gt(iv)gt(ii)gt(iii)`

Text Solution

Verified by Experts

The correct Answer is:
a.
ii. It has one `3^(@)C^(o+)` structure.
iii. It has one `3^(@)C^(o+)` structure.

`iv` It can rearrange to more stable `3^(@)C^(o+)`.
`i`. It has only one `2^(@)C^(o+)`.

So the decreasing order of dehydration is `:`
`(ii)gt(iii)gt(iv)gt(i).`
