In ethers, the `C-O-C` bond angle is

A

`180^@`

B

`90^@`

C

`110^@`

D

`160^@`

Text Solution

Verified by Experts

The correct Answer is:
C
The C - O - C bond angle is about 110° which is quite close to the normal tetrahedral (109°28') . In ethers, the repulsion between lone pair of electrons is counter balanced by the repulsion between the bulky alkyl groups.
