Which is the most covalent?
- A \(\mathrm{AlCl}_3\)
- B \(\mathrm{AlI}_3\)
- C \(\mathrm{MgI}_2\)
- D \(\mathrm{NaI}\)
Answer & Solution
Correct Answer
(B) \(\mathrm{AlI}_3\)
Step-by-step Solution
Detailed explanation
\(\mathrm{AlI}_3\) is the most covalent compound. According to Fajan's rule, covalent character \(\propto\) small cation or large anion or positive charge Since, lesser the electronegativity difference more covalent is aluminium halide. Hence, the most covalent halide is…
