Question

Identify the incorrect statement related to ${PCl_5}$ from the following:

• A. Axial P �Cl bonds are longer than equatorial P�Cl bonds
• B. ${PCl_5}$ molecule is non-reactive
• C. Three equatorial P - Cl bonds make an angle of 120� with each other
• D. Two axial P - Cl bonds make an angle of 180� with each other

Answer 1

Answer: (B)

${PCl_5}$ molecule is non-reactive

Answer 2

(1) True
(3) True
Axial bond : 240 pm
Equatorial bond : 202 pm
(4) False
Due to longer and hence weaker axial bonds, ${PCl_5}$ is a reactive molecule.
