Expert Answer:

1) Structure of PCl3:

 It has a pyramidal shape as shown, in which phosphorus is sp3 hybridised.

 

2) Structure of PCl5:

  • It has a trigonal bipyramidal structure, in gaseous and liquid phases.
  • The three equatorial P–Cl bonds are equivalent, while the two axial bonds are longer than equatorial bonds.
  • This is due to the axial bond pairs suffer more repulsion as compared to equatorial bond pairs
