Match the species in List-I with their geometry in List-II List-I A. PCl₅ B. BrF₅ C. BF₄⁻ D. [Ni(CN)₄]²⁻ List-II I. Tetrahedral II. Square Planar III. Trigonal bipyramidal IV. Square pyramidal Choose the correct answer from the options given below:
A
A-IV, B-III, C-I, D-II
B
A-III, B-IV, C-I, D-II
C
A-III, B-I, C-II, D-IV
D
A-III, B-II, C-I, D-IV
Explanation
(A) PCl₅ → Trigonal bipyramidal (sp³d) (B) BrF₅ → Square pyramidal (sp³d²) 1lp (C) BF₄⁻ → Tetrahedral (sp³) (D) [Ni(CN)₄]²⁻ → dsp² ⇒ square planar
