The oxygen, nitrogen, and fluorine bonds with hydrogen to produce molecules, these molecules are fascinated towards each other by hydrogen bonds.
A hydrogen bond refers to a partially electrostatic attraction amid a hydrogen atom that is combined with a more electronegative group or atoms like oxygen, nitrogen, or fluorine. In this bonding, one is known as the hydrogen bond donor, and another atom adjacent to it exhibiting a lone pair of electrons is known as the hydrogen bond acceptor.
