What forces are present in CH3CH2NH2?

In CH3CH2NH2 (ethylamine), the primary forces present are hydrogen bonding, dipole-dipole interactions, and London dispersion forces. The nitrogen atom in the amine group can form hydrogen bonds with hydrogen atoms of other molecules due to its electronegativity, leading to stronger intermolecular interactions. Additionally, the polar C-N bond contributes to dipole-dipole interactions. London dispersion forces are also present but are generally weaker compared to hydrogen bonds and dipole-dipole interactions.
