Question

which of the following will have highest covalent character? LiCl, NaCl, KCl, RbCl​

Answer 1

Answer:

bro it is nacl

Explanation:

plz mark me as brilliant

Answer 2

The size of the cations determines the covalent nature of every molecule. The polarizing power of a cation is proportional to its size, and hence the covalent nature is proportional to its size. As the size of the cation grows larger, the covalent property diminishes.

The covalent nature of the molecule reduces as the size of the cation rises. The decreasing order of covalent character for Alkaline Earth Metal chloride compounds

RbCl > LiCl > NaCl > KCl  is the decreasing order of covalent character.

As a result, LiCl has a higher covalent character than KCl, and as a result, KCl is more soluble in water due to its lower covalent character.
