Question #83c78

Answer 1

Hydrogen bonds are the intermolecular (present between molecules) interactions.

Explanation:

Hydrogen Bonding in Water (`H_2O`):

Firstly, a water molecule contains two hydrogen atoms and one oxygen atom. The oxygen atom, being more electronegative, attracts the shared pairs of electrons more towards itself. As a result, oxygen gets a partial negative charge and hydrogen gets a partial positive charge.

Secondly, oxygen has two lone pairs of electrons. Moreover, hydrogen creates a strong electric field due to its small size. Thus, an oxygen atom of one `H_2O` molecule links to the hydrogen atom of another `H_2O` molecule through a lone pair of electrons. This attraction is called a hydrogen bond.
