Consider the following species : SOCl2,XeOF4,ClF3,ClF5,XeF5+,SO32−,XeF3+,SF4 List-I contains different molecular shapes and List-II contains total number of species with the same molecular shapes from the given species. Match each entry in List-I with the appropriate entry in List-II and choose the correct option.

(Q)
T-Shaped
(2)
two
(R)
Trigonal Planar
(3)

(A)P→1;Q→2;R→5;S→3✓ Correct
(B)P→5;Q→4;R→2;S→3
(C)P→3;Q→2;R→1;S→4
(D)P→1;Q→3;R→5;S→4
Answer: (A)
Solution
Analyzing each species:
See-saw (P):SF4 → 1 species
T-shaped (Q):ClF3, XeF3+ → 2 species
Trigonal Planar (R): None of the given species → 0 species
Square Pyramidal (S):XeOF4, ClF5, XeF5+ → 3 species
Other shapes:
SOCl2: Pyramidal
SO32−: Pyramidal
Correct matching: P→1; Q→2; R→5; S→3
