Answer: hydrogen atom of a polarized molecule bonds with an electro negative atom.

Explanation:

Hydrogen bonds are special type of dipole dipole forces which are formed when hydrogen bonds with an electro negative element. Hydrogen bonds are strongest type of bonds .Example: Bond between Oxygen of one water molecule to the hydrogen of another water molecule as shown in the image below.

Covalent bonds are formed by sharing of electrons among non metals.

Ionic bond is formed by transfer of electrons between metals and non metals.
