Question

Choose the correct option from the following:

• A. KF is more covalent than KI
• B. SnCl\textsubscript{2} is less covalent than SnCl\textsubscript{4}
• C. LiF is more covalent than KF
• D. ZnCl\textsubscript{2} is less covalent than NaCl

Hint:

Use Fajan’s Rule: Smaller cation and larger anion = more covalent bond.

Answer 1

The Correct Option is C

According to Fajan’s rule, smaller cation + larger anion → more covalent character.
Li\textsuperscript{+} is smaller than K\textsuperscript{+}, so LiF has more covalent character than KF.
Other statements are incorrect based on oxidation states and ionic sizes.
