$B > P > As > Bi$

Vedclass · Answer

(B) The correct order is $BCl_3 > PCl_3 > AsCl_3 > BiCl_3$. $BCl_3$ has a trigonal planar geometry with a bond angle of $120^{\circ}$ due to $sp^2$ hybridization. In the case of $PCl_3$,$AsCl_3$,and $BiCl_3$,the central atom is $sp^3$ hybridized with one lone pair,resulting in a pyramidal geometry. As we move down the group from $P$ to $Bi$,the electronegativity of the central atom decreases,causing the bond pairs to move further away from the central atom. Consequently,the bond angle decreases as we move down the group.

List-$I$	List-$II$
$(A)$ $PCl_3$	$(I)$ Square planar
$(B)$ $BF_3$	$(II)$ $T$-shape
$(C)$ $ClF_3$	$(III)$ Trigonal pyramidal
$(D)$ $XeF_4$	$(IV)$ See-saw
	$(V)$ Trigonal planar

In compounds of type $ECl_3$,where $E = B, P, As$ or $Bi$,the angles $\angle Cl-E-Cl$ for different $E$ are in the order
