Question

Assertion: Bond angle in ethers is slightly less than the tetrahedral angle.

Reason: There is a repulsion between the two bulky $(-R)$ groups.

• A. Assertion and reason both are wrong statements.
• B. Assertion and reason both are correct, and reason is correct explanation of assertion.
• C. Assertion is correct statement, but reason is wrong statement.
• D. Both assertion and reason are correct statements, but reason is not correct explanation of assertion.
• E. Assertion is wrong statement, but reason is correct statement.

Answer 1

The correct option is E

Assertion is wrong statement, but reason is correct statement.

Assertion

The $C-O-C$ bond angle in ether is slightly greater than the tetrahedral angle.

So, the assertion is an incorrect statement.

Reason:

This is due to the repulsive interaction between the two bulky alkyl groups.

So, the reason is a correct statement.



Hence, the assertion is an incorrect statement, but the reason is a correct statement.
