. The hybridisation in PC15 molecule is

The hybridisation in PC15 molecule is:

A: sp3

B: sp3d2

C: sp3d

D: sp2


Best Answer


  • The valence electrons of phosphorus are five.
  • Because each chlorine atom shares one electron, the PC15 molecule possesses sp3d hybridization and so it has a trigonal bipyramidal structure.
  • The first three orbitals,1s,3p,and 1d, are available for hybridization.
  • As a result, a set of 5sp3d hybrid orbitals oriented to the five corners of a trigonal bipyramidal can be obtained.


Final answer:

Hence, the correct option is C, i.e. sp3d .
