Q. Identify the incorrect statement related to $PCl_5$ from the following :
A) Three equatorial P-Cl bonds make an angle of 120° with each other
B) Two axial P-Cl bonds make an angle of 180° with each other
C) Axial P-Cl bonds are longer than equatorial P-Cl bonds
D) $PCl_5$ molecule is non-reactive
Explanation
[Solution] The longer, weaker axial bonds make $PCl_5$ reactive (e.g. it readily loses $Cl_2$ and chlorinates). Answer (4).
