Question

The correct increasing covalent nature is:

• A. $NaCl<LiCl<BeC{l}_2$
• B. $BeC{l}_2<NaCl<LiCl$
• C. $BeC{l}_2<LiCl<NaCl$
• D. $LiCl<NaCl<BeC{l}_2$

Answer 1

The correct option is A $NaCl<LiCl<BeC{l}_2$

Covalent nature is favoured by small-sized cation and large-sized anion.

Also, the covalent nature is favoured by cations possessing large charges.

Hence, the increasing order of the covalent nature is $NaCl<LiCl<BeC{l}_2$.
