In BrF ₃ molecule, the lone pairs occupy equatorial positions to minimize:

Options

  1. Alone pair-bond pair repulsion only
  2. Bbond pair-bond pair repulsion only
  3. Clone pair-lone pair repulsion and lone pair-bond pair repulsion
  4. Dlone pair Ione pair repulsion only

Correct answer

C. lone pair-lone pair repulsion and lone pair-bond pair repulsion

Step-by-step solution

In 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 BrF ₃ molecular geometry is said to be T-shaped or Trigonal bipyramidal
