Assertion: The bond angle in alcohols ...

Assertion: The bond angle in alcohols is slightly less than the tetrahedral angle.
Reason: In alcohols, the oxygen.of -OH group is attached to carbon by a sigma bond formed by the overlap of a `sp^3` hybridised orbital of carbon with `sp^3` hybridised orbital of oxygen.

Text Solution

Verified by Experts

The correct Answer is:
B
The bond angle in alcohols is slightly less than the tetrahedral angle due to the repulsion between the unshared electronpairs of oxygen.
