Question

Identify the incorrect statement related to PCl₅ from the following:

Options

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

• 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 molecule is non-reactive.

Answer 1

PCl₅ molecule is non-reactive.

Explanation:

PCl₅ is quite reactive. It readily hydrolyses in water and reacts with many substances like alcohols and metals. The rest of the statements about its trigonal bipyramidal structure and bond angles are correct.
