Question

why pcl5 is more reactive

Answer 1

In pcl5 there are two types of pcl bonds:- axial bonds and equitorial bonds. It is found that axial bonds are longer than equitorial bonds .Due to unequal bonds pcl5 is unstable and highly reactive.

Answer 2

Reasons for more reactive of $PCl_5$

• The structure of $PCl_5$ has two types of bonding namely equatorial bonds and axial bonds.
• The equatorial bonds lie in the same plane and appear linear.
• On the other hand, the axial bond is longer than the equatorial bonds due to which it is weak as well as experience a high force of repulsion.
• Due to the above-mentioned factors, $PCl_5$ is more reactive.
