In copper sulphate pentahydrate (CuSO4.5H2O), the number of water molecules attached with Cu+2 ion through coordinate covalent bond is:
Correct answer: B. 4
- A. 2
- B. 4
- C. 3
- D. 5
Explanation
Copper Sulfate Pentahydrate Structure: In CuSO₄·5H₂O, the copper ion (Cu²⁺) is surrounded by five water molecules.Coordinate Covalent Bonds: Four of these water molecules coordinate with the copper ion, forming coordinate covalent bonds. The fifth water molecule is typically not directly bonded to the copper ion but instead is involved in hydrogen bonding and stabilizing the structure.

About Transition Elements
Transition elements are identified by their partially filled d subshells in atoms or common ions. The topic covers the electronic structure of d-block elements, including the filling order of 4s and 3d orbitals, variable oxidation states and the distinction between transition elements and elements with completely filled d subshells.
