Question

In the molecule of the type $AX _{2} L _{ n }$ (where $L$ represents lone pairs $\& n$ its number), there exists a bond $b / w$ element $A \& X .$ The $\angle XAX$

• A. Always decreases if n increases
• B. Always increases if n increases
• C. Will be max. for n=3
• D. Generally decreases if n decreases

Answer 1

Answer: (C)

$XeF _{2} L _{3}$ is a perfect example for molecule of the type $AX _{2} L _{ n }$ where bond angle is maximum when value of $n=3$
