(i) Are all the five bonds in $PCl_5$ molecules equivalent ? justify your answer. (ii) What happens when $PCl_5$ is heated ?

Question

$\begin{array}{1 1}\text{(a) (i)The four equatorial P - Cl bonds are equivalent , while the one axial bonds are different and longer than equatorial bonds .(ii) $PCl_5\Rightarrow PCl_2+Cl$}\\\text{(b)(i)The three equatorial P - Cl bonds are equivalent , while the two axial bonds are different and longer than equatorial bonds .(ii) $PCl_5\Rightarrow PCl_2+Cl_2$}\\ \text{(c) (i)The three equatorial P - Cl bonds are equivalent , while the two axial bonds are different and longer than equatorial bonds .(ii) $PCl_5\Rightarrow PCl_3+Cl_2$} \\ \text{(d) (i)All the Five equatorial P - Cl bonds are equivalent , .(ii) $PCl_5\Rightarrow PCl_3+Cl_2$}\end{array}$
