Consider the intermolecular forces present in a pure sample of each of the following compounds: $C{H}_{3}C{H}_{2}C{H}_{2}N{H}_2$ and $C{H}_{3}C{H}_{2}C{O}_{2}H.$ Identify the intermolecular forces that these compounds have in common.

A Dipole$-$dipole forces and hydrogen bonding.

B

Dipole$-$dipole forces only.

C

Dispersion forces, dipole$-$dipole forces, and hydrogen bonding.

D Dispersion forces and dipole$-$dipole forces
