Problem

There are two groups of compounds A and B. Group A contains three compounds

Px_4, Qy_3, Rz_2

. Group B also contains three compounds

Sx_4, Ty_3, Uz_2

. Hybridization of each central atom of group A compounds is same as that of iodine in

I\text{BrCl}^-

while in group B compounds it is same as that of iodine in

I\text{BrCl}^+

. Substituents X, Y and Z exhibit covalency of one in ground state. Then find the value of

x/y

. Where,

x

and

y

are total number of lone pairs present at central atoms of compounds of group A and B respectively.
