The hydrogen bonding ability of the isomeric `1^(@),2^(@)` and `3^(@)` alcohols decreases in the order

A

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

B

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

C

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

D

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

Text Solution

Verified by Experts

The correct Answer is:
D
The hydrogen bonding ability of the isomeric alcohols decreases as the number of alkyl groups attached to the carbon atom carrying the `-OH` group increases.
