Identify the incorrect statement related to PCl
5
from the following:
- AThree equatorial P–Cl bonds make an angle of 120
∘
with each other - BTwo axial P–Cl bonds make an angle of 180
∘
with each other - CAxial P–Cl bonds are longer than equatorial P–Cl bonds
- DPCl
5
molecule is non-reactive
Solution & Step-by-step Explanation
PCl
5
has a trigonal bipyramidal geometry (sp
3
d).
Equatorial angles are 120
∘
; Axial angle is 180
∘
.
Axial bonds are longer than equatorial bonds because they experience more repulsion from the equatorial bond pairs.
Incorrect Statement: PCl
5
is highly reactive (e.g., it reacts violently with water and decomposes upon heating to PCl
3
and Cl
2
).
