Question

240] C — Cl bond is stronger than C — I bond, because
a] C — Cl bond is more ionic than C— I
b] C — CI bond is polar covalent bond
c] C — CI bond is more covalent than C —I
d] C —CI bond length is longer than C — I

Answer 1

Dear student,
The average bond energy of C-Cl is 328Kj/mol while that of C-I bond is 240Kj/mol. That means C-Cl bond is more covalent than C-I bond.
Therefore, C-Cl bond is stronger than C-I bond because C-Cl bond is more covalent than C-I .
