The molecule/ion with square pyramidal shape is:

Options

  1. ANi ( CN ) 4 2 -
  2. BPCl 5
  3. CBrF 5
  4. DPF 5

Correct answer

C. BrF 5

Step-by-step solution

BrF 5 is an interhalogen compound, meaning that the molecules of this compound contain two or more different halogen atoms but no atoms of the elements belonging to any other group. The hybridisation of bromine pentafluoride forms an sp 3 d 2 hybridisation, resulting in a square pyramidal molecular structure. The hybrid molecule has five sigma bonds due to the covalent electron sharing.
