The order of covalent character of KF, KI, \(\mathrm{KCl}\) is
- A \(\mathrm{KCl} < \mathrm{KF} < \mathrm{Kl}\)
- B \(\mathrm{Kl} < \mathrm{KCl} < \mathrm{KF}\)
- C \(\mathrm{KF} < \mathrm{KI} < \mathrm{KCl}\)
- D \(\mathrm{KF} < \mathrm{KCl} < \mathrm{Kl}\)
Answer & Solution
Correct Answer
(D) \(\mathrm{KF} < \mathrm{KCl} < \mathrm{Kl}\)
Step-by-step Solution
Detailed explanation
Covalent character increases with increase in size of anion or decrease with size of cation. As, here cation \(\left(\mathrm{K}^{+}\right)\)in all the species is common, hence the covalent character will increase in the order as: \(\mathrm{KF} < \mathrm{KCl} < \mathrm{Kl}\).
