In BrF3 molecule, the lone pairs occupy equatorial positions to minimize
  1. A
    lone pair - bond pair repulsion only
  2. B
    bond pair - bond pair repulsion only
  3. C
    lone pair - lone pair repulsion and lone pair - bond pair repulsion
  4. D
    lone pair - lone pair repulsion only.

Correct answer: D

Lone pair - Lone pair repulsion > lone pair - bond pair repulsion > bond pair-bond pair repulsion.

The lone pairs of electrons are arranged on equatorial position as they are at maximum distance at these positions and hence they have minimum repulsion at these positions.
