Question

The types of bonds present in $CuS{O}_4.5H_{2}O$ are only:

• A. electrovalent and covalent
• B. electrovalent and coordinate covalent
• C. electrovalent, covalent and coordinate covalent
• D. covalent and coordinate covalent

Answer 1

The correct option is C electrovalent, covalent and coordinate covalent

The structure of $CuS{O}_4.5H_{2}O$ in the solid-state is shown above. The $C{u}^{2+}$ ions are attracted towards $S{O}_4^{2-}$ ions not only by ionic interactions (electrovalent) but also by coordinate covalent bonds.

The $C{u}^{2+}$ ions form coordinate covalent bonds with water as well as sulfate ions. There are covalent bonds in water and sulfate ions.
