Give reasons for the following: PbCl_4 is more covlalentthan PbCl_2 . – InterviewSolution

1.	Give reasons for the following: PbCl_4 is more covlalentthan PbCl_2 .
Answer» Solution :A covalent COMPOUND is formed by sharing of ELECTRONS and an ionic compound is formed by transfer of electrons. It is energetically not feasible for Pb to LOSE 4 electrons to form `PbCl_4`. Hence, it shares four electrons with four CHLORINE atoms to form `PbCl_4`. On the other hand, Pb can lose two electrons to two chlorine atoms and form ionic `PbCl_2`.
