Identify the incorrect statement related to

PC{l}_{5}

from the following: Identify the incorrect statement related to PC l _ 5 from the following:

Options

AThree equatorial $P - Cl$ bonds make an angle of ${120}^{o}$ with each other
BTwo axial $P - Cl$ bonds make an angle of ${180}^{o}$ with each other
CAxial $P - Cl$ bonds are longer than equatorial $P - Cl$ bonds
D ${PCl}_{5}$ molecule is non-reactive

Correct answer

D. ${PCl}_{5}$ molecule is non-reactive

Step-by-step solution

Identify the incorrect statement related to PC l _ 5 from the following:
(i) Three equatorial $P - Cl$ bonds make an angle of $120 °$ with each other is correct.

(ii) Two axial $P - Cl$ bonds make an angle of $180 °$ with each other.

(iii) Axial $P - Cl$ bonds are longer than equatorial because according to Bent’s rule the hybrid orbitals that contain more $p -$ character or less $s -$ character are placed on axial position and have more bond length.

(iv) $PC{l}_{5}$ molecule is reactive (W) is the incorrect answer.
