For which of the following molecule significant µ ≠ 0?

Consider the following compounds.

(i) ICl                            (ii) IBr                           (iii) ICl₃                   

(iv) IF₅                               (v) BrF₃                        (vi) IF₃  

(vii) BrF₅                       (viii) IF₇

Calculate the value of $\text{[}\frac{{\mathrm{P}}^2-{\mathrm{Q}}^2}{\mathrm{R}+\mathrm{S}}]$

P  : Total number of polar compounds

Q  : Total number of planar compounds

R  : Total number of non polar compounds

S  : Total number of non planar compounds
