Identify the incorrect statement related to PCl5 from the following:

  • Two axial P–Cl bonds make an angle of 180° with each other

  • Axial P–Cl bonds are longer than equatorial P–Cl bonds

  • PCl5 molecules in non-reactive

  • Three equatorial P–Cl bonds make an angle of 120° with each other


C.

PCl5 molecules in non-reactive

(1) True    

(2) True: Axial bond : 240 pm
             Equatorial bond : 202 pm

(3) False: Due to longer and hence weaker axial bonds, PCl5 is a reactive molecule.

(4) True
