Let's analyze the types of bonds present in $CuS{O}_4\cdot 5H_{2}O$.

• Electrovalent (Ionic) Bonds: These bonds are formed by the complete transfer of electrons between atoms, typically between a metal and a non-metal. In $CuS{O}_4$, copper (Cu) is a metal and sulfate ($S{O}_4^{2-}$) is a polyatomic anion. The $C{u}^{2+}$ ion and the $S{O}_4^{2-}$ ion are held together by electrovalent bonds.
• Covalent Bonds: These bonds are formed by the mutual sharing of electrons between atoms. Within the sulfate ion ($S{O}_4^{2-}$), sulfur and oxygen atoms are bonded together by covalent bonds. Also, within the water molecules ($H_{2}O$), hydrogen and oxygen atoms are bonded by covalent bonds.
• Co-ordinate Covalent (Dative) Bonds: These are special types of covalent bonds where both shared electrons are contributed by only one atom. In $CuS{O}_4\cdot 5H_{2}O$, four water molecules are directly coordinated to the $C{u}^{2+}$ ion, forming $[Cu(H_{2}O{)}_4{]}^{2+}$. The oxygen atom of each water molecule donates a lone pair of electrons to the empty d-orbitals of the $C{u}^{2+}$ ion, forming co-ordinate covalent bonds. The fifth water molecule is involved in hydrogen bonding, but hydrogen bonds are not typically classified as primary chemical bonds (electrovalent, covalent, co-ordinate covalent) in this context.

Therefore, all three types of bonds – electrovalent, covalent, and co-ordinate covalent – are present in $CuS{O}_4\cdot 5H_{2}O$.

Option Analysis:

• A) electrovalent and covalent: This is incorrect because it misses the co-ordinate covalent bonds.
• B) electrovalent and co-ordinate covalent: This is incorrect because it misses the covalent bonds within the sulfate ion and water molecules.
• C) electrovalent, covalent and co-ordinate covalent: This is correct as it includes all three types of bonds.
• D) covalent and co- ordinate covalent: This is incorrect because it misses the electrovalent bonds between $C{u}^{2+}$ and $S{O}_4^{2-}$.

Correct Answer: (C)
