Let us consider the molecules given below:
NF₃, NCl₃, NBr₃,
PF₃,PCl₃, PBr₃,
AsF₃, AsCl₃, AsBr₃.
If $a$ is the number of molecules having a bond angle greater than that of AsH₃, and
$b$ is the number of molecules having a bond angle greater than AsF₃,
find the value of $\frac{a + b}{2}$ .

Question

Let us consider the molecules given below:

NF₃, NCl₃, NBr₃,
