Question

Which of the following types of bonds are present in $CuS{O}_4\cdot 5H_{2}O$?
I: Electrovalent II: Covalent III: Coordinate

• A. I, II
• B. II, III
• C. I, III
• D. I, II, III

Answer 1

The correct option is D I, II, III

Here, $CuS{O}_4$ is ionic compound. When it is hydrated, it forms hydrogen bonding with one of the water molecule and coordinate bonds with the other 4 water molecules. It has covalent bonding in $S{O}_4^{2-}$.

∴CuSO4.5H2O contains all the three types of bond

i. Electrovalent (Ionic interaction between $C{u}^{2+}$ & $S{O}_4^{2-}$)

ii.Covalent (with $S{O}_4^{2-}$)

iii.Co ordinate (H2O molecules to $C{u}^{2+}$)
