This problem is asking for the intermolecular forces in ethanamine, C₂H₅NH₂. Hence, after analyzing it, we find they are both London dispersion forces and hydrogen bonding.
<h3>Intermolecular forces</h3>
In chemistry, intermolecular forces are the responsible of holding molecules together both in liquids and solids, and they depend on the type of bonds exhibited by the molecule. In this case, ethanamine:
Has C-C, C-H, C-N and N-H bonds. Now, C-C, C-H and N-H are strongly nonpolar as they have an electronegativity difference below 0.7, which means ethanamine has London dispersion forces as the weakest ones.
In addition, the presence of N-H bonds, provides this molecule with stronger intermolecular forces, hydrogen bonding, which occur in N-H and O-H bonds.
