Which of the following is directional bond?
Correct answer: C. H-bond
- A. Ionic bond
- B. Metallic bond
- C. H-bond
- D. None of these
Explanation
A hydrogen bond (or H-bond) is a primarily electrostatic force of attraction between a hydrogen (H) atom which is covalently bound to a more electronegative "donor" atom or group (Dn), and another electronegative atom bearing a lone pair of electrons-the hydrogen bond acceptor (Ac).Thus, the bond is directed from the partially positive hydrogen atom towards the partially negative fluorine, oxygen, or nitrogen atom. Therefore we can say that a hydrogen bond is directional.

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.
