Question

Assertion: The bond angle of $PB{r}_3$ is greater than $P{H}_3$ but the bond angle of $NB{r}_3$ is less than $N{H}_3$.
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 $PB{r}_3$ is lesser than $P{H}_3$

but the bond angle of $NB{r}_3$ is greater than $N{H}_3$.

Size of Br is larger than hydrogen.
