Question

The compound showing minimum ionic character is kcl rbcl cscl zncl2

Answer 1

hey mate
bcoz of d 10 electronic configuration in
zncl2 molecule it has maximum covalent character

and thus subsequently it has minimum ionic character also.... among all of these given compounds

Answer 2

The compound showing minimum ionic character is ZnCl2. It can be explained by Fajan's rule.

                According to Fajan's rule,the cations having completely filled d subshell or pseudo inert gas shell configuration have very high polarising power.Greater the polarising power,higher the covalent character of its compound. In the above compounds,only zinc has filled 10 d electrons and hence  ZnCl2 has minimum ionic character.
