Match List-I with List-II regarding the shape/geometry of the given compounds.
Column I
- A. $NH_3$
- B. $BrF_5$
- C. $XeF_4$
- D. $SF_6$
Column II
- I. Trigonal Pyramidal
- II. Square Planar
- III. Octahedral
- IV. Square Pyramidal
Correct answer: A → I, B → IV, C → II, D → III
Solution
$NH_3$: 3 bond pairs + 1 lone pair ($sp^3$) – trigonal pyramidal
$BrF_5$: 5 bond pairs + 1 lone pair ($sp^3d^2$) – square pyramidal
$XeF_4$: 4 bond pairs + 2 lone pairs ($sp^3d^2$) – square planar
$SF_6$: 6 bond pairs ($sp^3d^2$) – octahedral
Correct match: A-I, B-IV, C-II, D-III.
