Question

The bonds present in CuSO₄.5H₂O are

(A) electrovalent and covalent

(B) electrovalent and co-ordinate covalent

(C) electrovalent, covalent and co-ordinate covalent

(D) covalent and co-ordinate covalent

Answer 1

Correct option is (C) electrovalent, covalent and co-ordinate covalent

The structure of \(CuSO_4.5H_2O\) in the solid-state is shown above. The \(Cu^{2 +}\) ions are attracted towards \(SO_4^{2-}\) ions not only by ionic interactions (electrovalent) but also by coordinate covalent bonds.

The \(Cu^{2 +}\) ions form coordinate covalent bonds with water as well as sulfate ions. There are covalent bonds in water and sulfate ions.
