Identify the incorrect statement related to ${PCl_5}$ from the following:
Identify the incorrect statement related to ${PCl_5}$ from the following:
Updated On: May 17, 2024
- Axial P �Cl bonds are longer than equatorial P�Cl bonds
- ${PCl_5}$ molecule is non-reactive
- 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
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
(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.
(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.

P-Block Elements
- P block elements are those in which the last electron enters any of the three p-orbitals of their respective shells. Since a p-subshell has three degenerate p-orbitals each of which can accommodate two electrons, therefore in all there are six groups of p-block elements.
- P block elements are shiny and usually a good conductor of electricity and heat as they have a tendency to lose an electron. You will find some amazing properties of elements in a P-block element like gallium. It’s a metal that can melt in the palm of your hand. Silicon is also one of the most important metalloids of the p-block group as it is an important component of glass.
P block elements consist of:
- Group 13 Elements: Boron family
- Group 14 Elements: Carbon family
- Group 15 Elements: Nitrogen family
- Group 16 Elements: Oxygen family
- Group 17 Elements: Fluorine family
- Group 18 Elements: Neon family
