In hydronium ion, what is the nature of bond between oxygen of water and hydrogen ion in an acidic solution?
Correct answer: D. Coordinate covalent bond
- A. Covalent
- B. Electrovalent
- C. Hydrogen bond
- D. Coordinate covalent bond
Explanation
Coordinate covalent bond: A coordinate covalent bond is formed when one atom donates a pair of electrons to be shared with another atom. In the hydronium ion, the oxygen atom of water donates a pair of electrons to form a bond with the hydrogen ion, resulting in a coordinate covalent bond.

About Sigma and Pi Bonds
A sigma bond forms by direct end-to-end overlap along the internuclear axis, whereas a pi bond forms by sideways overlap of parallel orbitals. The topic covers single, double and triple bonds, bond composition, restricted rotation and the relation between sigma and pi bonding and orbital hybridisation.
