Each row describes a neutral main-group chloride with only single central bonds and monovalent Cl ligands. Infer n (bonded Cl count) and m (central lone pairs) from the group and geometry, using a zero-formal-charge Lewis structure.

Calculate (Σn+Σm)(Σn−Σm). All sums run over the four rows.

List-I

List-II

[P] AClₙ: group16 centre, bent

[1] Record inferred n and m for P

[Q] BClₙ: group15 centre, trigonal pyramidal

[2] Record inferred n and m for Q

[R] CClₙ: group14 centre, tetrahedral

[3] Record inferred n and m for R

[S] DClₙ: group17 centre, T-shaped

[4] Record inferred n and m for S

Answer:
119
Solution:

P has n=2, m=2; Q3, 1; R4, 0; S3, 2. Thus Σn=12 and Σm=5. The requested product is 17×7=119. The T-shaped group17 member has five electron domains and two lone pairs, unlike the group15 pyramid.
