Question:
Assertion (A): The bond angle C-O-C in ethers is slightly greater than tetrahedral angle.
Reason (R): This is because of the repulsive interaction between the two bulky alkyl groups.

Solution and Explanation
The bond angle in ethers is slightly greater than the tetrahedral angle due to the lone pairs of
electrons on the oxygen atom, which push the bonding pairs away, increasing the bond angle.
However, the reason given regarding the repulsive interaction between bulky alkyl groups is
incorrect; the main factor is the lone pair-bond pair repulsion.
