Match the interhalogen compounds of column-I with the geometry in column-II and assign the correct code. Column-I: 1. XX′ 2. XX′3 3. XX′5 4. XX′7 Column-II: (i) T-shape (ii) Pentagonal bipyramidal (iii) Linear (iv) Square-pyramidal (v) Tetrahedral Code:

1. (a) (iii) (i) (iv) (ii)
2. (b) (v) (iv) (iii) (ii)
3. (c) (iv) (iii) (ii) (i)
4. (d) (iii) (iv) (ii) (i)

Correct answer: (a) (iii) (i) (iv) (ii)

Solution

Interhalogen compounds have geometries based on VSEPR theory. XX′ is linear (sp hybridization), XX′3 is T-shaped (sp3d hybridization), XX′5 is square-pyramidal (sp3d2 hybridization), and XX′7 is pentagonal bipyramidal (sp3d3 hybridization).
