What is a hydrogen bond?

THIS IS THE BEST ANSWER 👇

Hydrogen bonding occurs when a hydrogen atom is covalently bonded to an NN, OO, or FF atom.

A hydrogen atom receives a positive partial charge when it is covalently bonded to an FF atom.

A hydrogen bond can be made with only certain compounds that contain hydrogen.

Explanation:

Hydrogen bonding does not occur in all compounds containing hydrogen. Hydrogen bonds are only found in those compounds where hydrogen is linked to a highly electrified element such as fluorine, oxygen or nitrogen.

In a specie under a hydrogen bond, hydrogen receives a positive partial charge and the electronegative element receives a negative partial charge that extends across the molecule.
