Correct answer: (a) MCl2 is more ionic than MCl4
Explanation:
Metal atom in the lower oxidation state forms the ionic bond and in the higher oxidation state the covalent bond because higher oxidation state means small size and great polarizing power and hence greater the covalent character. Hence MCl2 is more ionic than MCl4.
