Vedclass · Answer

(C) According to $Fajan's \ rule$,the covalent character of an ionic bond increases with an increase in the polarizing power of the cation. Polarizing power is directly proportional to the charge density of the cation (charge/size ratio). Comparing the cations $Na^+$,$Li^+$,and $Be^{2+}$: $1$. $Na^+$ has a charge of $+1$ and a larger ionic radius. $2$. $Li^+$ has a charge of $+1$ and a smaller ionic radius than $Na^+$. $3$. $Be^{2+}$ has a higher charge of $+2$ and the smallest ionic radius among the three. Thus,the polarizing power increases in the order: $Na^+ Consequently,the covalent character increases in the order: $NaCl < LiCl < BeCl_2$.

The correct sequence of increasing covalent character is represented by:
