Question

Bonds present in $CuS{O}_4.5H_{2}O\left(s\right)$ are:

• A. Electrovalent and covalent
• B. Electrovalent and coordinate
• C. Electrovalent, covalent and coordinate
• D. Covalent and coordinate

Answer 1

The correct option is C Electrovalent, covalent and coordinate

In hydrated copper sulphate molecule ($CuS{O}_4.5H_{2}O$), there exists ionic (or electrovalent) bonding between $C{u}^{2+}$ and $S{O}_4^{2-}$ ions while the bonds between $S$ and $O$ in sulphate ion is purely covalent. Water molecules act as ligands forming coordinate bonds with the central metal ion.
