The correct order of increasing ionic character is

Options

A. `BeCl_2 lt MgCl_(2) lt CaCl_(2) lt BaCl_(2)`
B. `BeCl_2 lt CaCl_(2) lt MgCl_(2) lt BaCl_(2)`
C. `BaCl_2 lt CaCl_(2) lt MgCl_(2) lt BeCl_(2)`
D. `MgCl_(2) lt CaCl_(2) lt BeCl_2 lt BaCl_(2)`

Answer

A

Explanation

Polarising power of `Be^(2+) gt Mg^(2+) gt Ca^(2+) gt Ba^(2+)`
Thus, ionic nature of `BeCl_(2) lt MgCl_(2) lt CaCl_(2) lt BaCl_(2)`
