The type of bonds present in CuSO₄.5H₂O are

The correct type of bonds present in CuSO₄·5H₂O (Copper(II) sulfate pentahydrate) are:

Electrovalent, covalent, and coordinate bonds

Detailed Explanation:

1. Electrovalent Bond:
   • The bond between Cu²⁺ and SO₄^2- is electrovalent (ionic). Copper(II) ion (Cu²⁺) is positively charged, while sulfate (SO₄^2-) is negatively charged. These ions are held together by electrostatic attraction.
2. Covalent Bond:
   • The bond between the oxygen and hydrogen atoms in the water molecules (H₂O) present in CuSO₄·5H₂O is covalent. The electrons are shared between the atoms to form these molecules.
3. Coordinate Bond:
   • The water molecules in CuSO₄·5H₂O also form coordinate bonds with the Cu²⁺ ion. The lone pair of electrons on the oxygen atom of water is donated to the copper ion, forming a coordinate bond.

Concept:

• Ionic (electrovalent) bonds form when there is an electrostatic attraction between oppositely charged ions (like Cu²⁺ and SO₄^2-).
• Covalent bonds occur when atoms share electrons (like in water molecules).
• Coordinate bonds are a type of covalent bond where both electrons in the shared pair come from the same atom, typically seen between metal ions and ligands (like water molecules in CuSO₄·5H₂O).
