In hydrogen bonding, the O-atom of water molecule forms a/an _ bond with the H-atom of another molecule by sharing its _ of electron.
Correct answer: B. Coordinate covalent, one lone pair
- A. Ionic, one
- B. Coordinate covalent, one lone pair
- C. Covalent, 2 lone pair
- D. All of these options are correct
Explanation
The answer is Coordinate covalent, one lone pair. In hydrogen bonding, the O-atom of water molecule forms a coordinate covalent bond with the H-atom of another molecule by sharing its one lone pair of electron. A coordinate covalent bond is a type of covalent bond in which one atom donates both electrons to the shared pair. In the case of hydrogen bonding, the O-atom of water donates its lone pair of electrons to the H-atom of another water molecule. This forms a weak bond between the two molecules.

About Hydrogen Bonding
Hydrogen bonding is the strong attraction between hydrogen attached to nitrogen, oxygen or fluorine and an electronegative atom in the same or another molecule. It explains unusual boiling points, viscosity, surface tension, water's properties and the difference between intermolecular and intramolecular hydrogen bonding.
