Explanation:
Detailed explanation-1: -Summary. Water molecules are polar, so they form hydrogen bonds. This gives water unique properties, such as a relatively high boiling point, high specific heat, cohesion, adhesion and density.
Detailed explanation-2: -Hydrogen bonding is an intermolecular force which occurs between two molecules which have a hydrogen atom directly bonded to a nitrogen, oxygen, or fluorine atom. So no, two hydrogen atoms alone cannot engage in hydrogen bonding.
Detailed explanation-3: -First molecules has hydrogen attached to a highly electronegative atom (N, O, F). (hydrogen bond donor) Second molecule has a lone pair of electrons on a small highly electronegative atom (N, O, F). (hydrogen bond acceptor) 27-Aug-2022
