Question

Hydrogen bonding occurs in molecules when a _____________. (1 point)

hydrogen atom forms a covalent bond with one other atom.
hydrogen atom forms covalent bonds with more than one atom.
hydrogen atom of a polarized molecule bonds with an electronegative atom
hydrogen atoms form an ionic bond with one other atom

Answer 1

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

Step-by-step 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.
