Question

Assertion (A) The $C-O$ bond length (141 pm) of ether is almost same as in alcohols.
Reason (R) The bond angle in ether is slightly greater than the tetrahedral angle due to repulsive interaction between the two bulky $(-R)$ groups.

• A. Both A and $R$ are correct; $R$ is the correct explanation of $A$.
• B. Both A and $R$ are correct; $R$ is not the correct explanation of $A$.
• C. $A$ is correct; $R$ is incorrect.
• D. $R$ is correct; $A$ is incorrect.

Answer 1

Answer: (B)

The bond angle in ether is slightly greater than the tetrahedral angle due to the repulsive interaction between the two bulky $(-R)$ groups. The $C - O$ bond length $(141\, pm )$ is almost the same as in alcohols.
