p-Block Elements (Class 12) · Class 12 · JEE Main Previous Year Question
The correct order of bond dissociation enthalpy of halogens is:
- a
- b
- c
- d✓
Strategy: Match noble gas species with their geometry or hybridization.
Step 1: Geometric Identification
- (2 BP + 3 LP): Linear (Hybridization: ).
- (4 BP + 2 LP): Square Planar ().
- (6 BP + 1 LP): Distorted Octahedral ().
- (3 BP + 1 LP): Pyramidal ().
Step 2: Conclusion Matching (A), (B), (C), (D) with the corresponding geometries gives the correct set.
