Number of lone pair(s) of electrons on central atom and the shape of molecule respectively, are:
  1. (A)0, triangular planar.
  2. (B)1, pyramidal.
  3. (C)2, bent T-shape.✓ Correct
  4. (D)1, bent T-shape

Answer: (C)

Solution

has 7 valence electrons from Br. With 3 F atoms bonded, there are 3 bonding pairs and 2 lone pairs, giving a steric number of 5 ( hybridization). With 2 lone pairs and 3 bonding pairs, the molecular geometry is bent T-shaped.
