Question

why the bond in licl is more covalent than NaCl ?​

Answer 1

Answer:

Both LiCl and NaCl ought to be ionic compounds but LiCl is covalent but NaCl is ionic.

This is because of the small size of cation and large size of anion in LiCl. Since, the size of cation is small, it's polarising power is large. And since the anion is small, it's polarisability is more. Since covalency of a compound is directly proportional to the polarising power of the cation and polarisability of anion, LiCl is covalent.

Whereas in case of NaCl, the size of both cation and anion are nearly same, so polarising power of Na is not as much as Li in LiCl and polarisability of Cl in NaCl is not as much as Cl in LiCl.

Therefore, LiCl is more covalent than NaCl.
