The bond length in $$LiF$$ will be:

Aless than that of $$NaF$$
Correct Answer
Bequal to that of $$KF$$
Cmore than that of $$KF$$
Dequal to that of $$NaF$$

Solution

$$LiF$$ is more covalent than $$NaF$$ and $$KF$$.
As covalent nature increases, bond length decreases. Bond length in $$LiF$$ is less than that of $$NaF$$ and $$KF$$. Size of $$Na^+$$ and $$K^+$$ is greater than $$Li^+$$. Bond length is given by distance between nucleus of two atoms.
