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.

Question

Write the structures of (A), (B), and (C) in the following reaction:
Reaction Scheme: \[ (C) \xleftarrow{\text{conc. } HNO_3} \text{Phenol} \xrightarrow{\text{dil. } HNO_3} (A) + (B) \]

Answer 1

The bond angle in ethers exceeds the tetrahedral angle because the oxygen atom's lone electron pairs repel the bonding pairs, widening the angle. The assertion that bulky alkyl groups are the primary cause is mistaken; lone pair-bond pair repulsion is the dominant factor.

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.
