In $\mathrm{BrF}_3$ molecule, the lone pairs occupy equatorial positions to minimize:

• A

  lone pair-bond pair repulsion only
• B

  bond pair-bond pair repulsion only
• Correct answer
  C

  lone pair-lone pair repulsion and lone pair-bond pair repulsion
• D

  lone pair Ione pair repulsion only

Solution

In $\mathrm{BrF}_3$ molecule, the lone pair occupies equatorial position to minimize lone pair-lone pair repulsion and lone pair-bond pair repulsion as per VSEPR theory.
Related Theory $\mathrm{BrF}_3$ molecular geometry is said to be T-shaped or Trigonal bipyramidal

Hence, the correct answer is option: 'C'.
