Question

Assertion: The bond angle of $PBr _{3}$ is greater than $PH _{3}$ but the bond angle of $NBr _{3}$ is less than $NH _{3}$.
Reason: Size of $Br$ is less than hydrogen.

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

Answer 1

Answer: (D)

The bond angle of $PBr_3$ is lesser than $PH_3$

but the bond angle of $NBr_3$ is greater than $NH_3$.

Size of Br is larger than hydrogen.
