Between CuO and CuS, which is more covalent and why?

Text Solution

Verified by Experts

Between CuO and CuS, CuS is more covalent. Since cation is same in both, the anion determines the extent of polarisation. Larger anions have greater polarizability. Between `O^(-2)` and `S^(-2)` ions, `S^(-2)` ion is the more polarizable. Greater polarizability imparts greater covalent character to the compound.
