Question

Give the applications of hydrogen bonds in organic molecules.

Answer 1

Hydrogen bond:

1. A hydrogen bond is an attraction between a hydrogen (H) atom covalently bonded to a more electronegative atom or group and another electronegative atom or group.
2. It is a sort of dipole-dipole attraction present between molecules with$\mathrm{O}-\mathrm{H}$, $\mathrm{N}-\mathrm{H}$and $\mathrm{H}-\mathrm{F}$ groups.
3. Hydrogen bonds are weak bonds.
4. Some applications of hydrogen bonds in organic molecules are because of the hydrogen bonding that can occur between water and the alcohol molecule, lower alcohols are soluble in water.
5. A compound's melting point rises when hydrogen bonds are present.
6. A compound having a hydrogen bond is more soluble as compared to other compounds.
7. A compound will be acidic it does not have a hydrogen atom because it will be easier to remove hydrogen ions from the compound.
