Vedclass · Answer

(B) In $PCl_{5}$,the geometry is trigonal bipyramidal. It contains three equatorial bonds and two axial bonds. The axial bonds are longer and weaker than the equatorial bonds due to greater repulsion. Therefore,upon heating,$PCl_{5}$ readily decomposes to form $PCl_{3}$ and $Cl_{2}$ gas. The reaction is: $PCl_{5} \xrightarrow{\Delta} PCl_{3} + Cl_{2}$.
