Question

Consider the following compounds and Calculate value of (P^2 - Q^2) / (R + S).
(i) BrF (ii) ICl (iii) BrF3 (iv) BrF5 (v) ICl3 (vi) IF3 (vii) IF5 (viii) IF7
Where 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

Correct answer: 6

**SOLUTION:** TOTAL COMPOUNDS = 8.
POLAR (P) = 7 (ALL EXCEPT IF7)
NON-POLAR (R) = 1 (IF7)
PLANAR (Q) = 5 (BRF, ICL, BRF3, ICL3, IF3)
NON-PLANAR (S) = 3 (BRF5, IF5, IF7)
(P^2 - Q^2) / (R + S) = (7^2 - 5^2) / (1 + 3) = (49 - 25) / 4 = 24 / 4 = 6.. Step 1: Recall that ionic bonds are non-directional because the electrostatic attraction between oppositely charged ions acts uniformly in all 3D directions. Covalent bonds are directional due to the specific orientation of overlapping atomic orbitals. Step 2: Among the choices, RbCl is a highly ionic alkali metal halide salt composed of Rb^+ and Cl^- ions, whereas NCl3, BeCl2, and BCl3 are covalent molecules. Step 3: Therefore, RbCl has non-directional bonds, matching option (b).
