Match the following

Column I

Species

i) IF7_7

ii) ClF3_3

iii) I3−_3^-

iv) BrF5_5

Column II

Geometry

p) Pentagonal bipyramidal

q) 'T' Shaped

r) Linear

s) Square pyramidal

A

i-p ii-q iii-r iv-s

B

i-q ii-p iii-s iv-r

C

i-s ii-r iii-p iv-q

D

i-r ii-s iii-q iv-p

Answer

Option A

Explanation

Solution

  1. IF₇: Has 7 bonded atoms, no lone pairs → Pentagonal bipyramidal
    → Match with p.

  2. ClF₃: Has 3 bonded atoms and 2 lone pairs on Cl → T-shaped
    → Match with q.

  3. I₃⁻: Has 3 atoms in a linear arrangement → Linear
    → Match with r.

  4. BrF₅: Has 5 bonded atoms and 1 lone pair → Square pyramidal
    → Match with s.

Thus, the correct matching is:
i → p, ii → q, iii → r, iv → s
