Detailed explanation-1: -This bond is called the hydrogen bond. As a result of hydrogen bonding, a hydrogen atom links the two electronegative atoms simultaneously, one by a covalent bond and the other by a hydrogen bond.

Detailed explanation-2: -In some polar molecules that contain hydrogen atoms, the partial positive charge of the hydrogen atoms of one molecule are attracted to the partial negative charge of an atom of a nearby molecule. This force of attraction is called a hydrogen bond.

Detailed explanation-3: -Polar Covalent Bonds. A polar covalent bond exists when atoms with different electronegativities share electrons in a covalent bond. Consider the hydrogen chloride (HCl) molecule. Each atom in HCl requires one more electron to form an inert gas electron configuration.

Detailed explanation-4: -In chemistry, 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).

Detailed explanation-5: -Polar molecules, specifically those containing fluorine, oxygen, or nitrogen covalently bonded to a hydrogen, are capable of forming a hydrogen bond with another fluorine, oxygen, or nitrogen in another molecule.
