$RbCl$ and $BeCl_2$

Vedclass · Answer

(C) According to Fajan's rule,ionic character depends on the polarising power of the cation.$Rb^+$ has the largest size among the given cations,resulting in the least polarising power and thus the greatest ionic character in $RbCl$.$Be^{2+}$ has the smallest size and highest charge density,giving it the highest polarising power,which results in the greatest covalent character and the least ionic character in $BeCl_2$.Therefore,the compounds with the greatest and least ionic character are $RbCl$ and $BeCl_2$ respectively.

Amongst $LiCl, RbCl, BeCl_2$ and $MgCl_2$,the compounds with the greatest and least ionic character respectively are:
