Identify the incorrect statement related to $PCl_5$ from the following:
A Three equatorial P–Cl bonds make an angle of $120^\circ$ with each other
B Two axial P–Cl bonds make an angle of $180^\circ$ with each other
C Axial P–Cl bonds are longer than equatorial P–Cl bonds
D $PCl_5$ molecule is non-reactive

Detailed Solution

$PCl_5$ has trigonal bipyramidal geometry. Three equatorial P–Cl bonds make an angle of $120^\circ$ with each other – true. Two axial P–Cl bonds make an angle of $180^\circ$ with each other – true. Axial bonds (240 pm) are longer than equatorial bonds (202 pm) – true. Due to the longer and hence weaker axial bonds, $PCl_5$ is a reactive molecule. So \"$PCl_5$ molecule is non-reactive\"" is the incorrect statement."
