Question

The order of covalent character of $KF,KI,KCl$ is

• A. KCl < KF < K
• B. KI < KCl < KF
• C. KF < KI < KCl
• D. KF < KCl < K

Answer 1

Answer: (D)

Covalent character increases with increase in size of anion or decrease with size of cation. As, here cation $\left(K^{+}\right)$ in all the species is common, hence the covalent character will increase in the order as: $KF<KCl<KI$.
