Question

Assertion: $HOF$ bond angle is higher than $HOCl$ bond angle in $HOX$.
Reason: Oxygen is more electronegative than halogens.

• A. If both Assertion: and Reason: are true and the Reason: is the correct explanation of the Assertion:
• B. If both Assertion: and Reason: are true but the Reason: is not the correct explanation of the Assertion:
• C. If Assertion: is true but Reason: is false
• D. If both Assertion: and Reason: are false

Answer 1

Answer: (D)

$HOCl$ bond angle is greater than $HOF$ bond angle. This is due to very small size of fluorine or due to $op-bp$ repulsion.
Oxygen is more electronegative than all halogens except fluorine (most electronegative).Thus, Assertion as well as Reason is incorrect.
