Vedclass · Answer

(B) According to Fajan's rule,ionic character is inversely proportional to the polarizing power of the cation.Polarizing power increases as the size of the cation decreases and its charge increases.Among the given cations ($Li^+$,$Rb^+$,$Be^{2+}$,$Mg^{2+}$),$Rb^+$ has the largest size and lowest charge,resulting in the lowest polarizing power and maximum ionic character.$Be^{2+}$ has the smallest size and high charge,resulting in the highest polarizing power and minimum ionic character.Therefore,$RbCl$ has the maximum ionic character and $BeCl_2$ has the minimum ionic character.

Amongst $LiCl$,$RbCl$,$BeCl_2$,and $MgCl_2$,the maximum and minimum ionic character will be shown by the compounds:
