Among LiCl, RbCl, BeCl2, MgCl2 the compounds which greater and least ionic character respectively are

Question

Among LiCl, RbCl, BeCl2, MgCl2 the compounds which greater and least ionic character respectively are (A)  LiCl and RbCl  (B)  RbCl and BeCl2  (C)  RbCl and MgCl-2  (D)  MgCl2 and BeCl2

RbCl and BeCl2, have greatest and least ionic character respectively. This is because, larger the cation, more is the ionic character or smaller the cation, greater is the covalent character (Fajan rules).

Q. Among $L i Cl, R b Cl, B e C l_{2}, M g C l_{2}$ the compounds which greater and least ionic character respectively are

$L i Cl$ and $R b Cl$

$R b Cl$ and $B e C l_{2}$

$R b Cl$ and $M g Cl - 2$

$M g C l_{2}$ and $B e C l_{2}$

$R b Cl$ and $B e C l_{2}$ , have greatest and least ionic character respectively. This is because, larger the cation, more is the ionic character or smaller the cation, greater is the covalent character (Fajan rules).
