Which of the following is the correct order of bond angle

$\begin{array}{1 1}(a)\;As I_3 > As Br_3 > As Cl_3&(b)\; As Cl_3 > As Br_3 > As I_3\\(c)\;As I_3 > As Cl_3 > As Br_3&(d)\;As Cl_3 > As I_3 > As Br_3\end{array}$

1 Answer

$As I_3 > As Br_3 > As Cl_3$
$AsI_3 \rightarrow 101^{\large\circ}$
$AsBr_3 \rightarrow 100.5^{\large\circ}$
$AsCl_3 \rightarrow 98.4^{\large\circ}$
Hence (a) is the correct answer.
