Which intermolecular interaction is predominant between ethylamine (CH3CH2NH2) and CH3OH?

Which intermolecular interaction is predominant between ethylamine (CH₃CH₂NH₂) and CH₃OH?

A. ion-dipole
B. dipole-dipole
C. hydrogen bonding
D. dispersion
E. dipole-induced dipole

Intermolecular forces are forced of attraction (usually) between molecules. Let’s go over the answer choices to figure out the correct intermolecular forces for CH₃CH₂NH₂ and CH₃OH?
Ion-dipole = exists between an ionic compound (metal+ nonmetal or metal + polyatomic ion or 2 polyatomic ions) and a polar molecule. Both molecules are not ionic, ruling this answer choice out.
Dipole-dipole = exists between two polar molecules. Both molecules are polar and have dipole-dipole intermolecular force between them but this is not the strongest force.
Hydrogen bonding = exists between molecules that have OH, NH or FH. Hydrogen bonding is the strongest type of dipole-dipole force. Both molecules are capable of hydrogen bonding (one molecule has NH and another has OH). This is the correct answer choice.
Dispersion = all molecules have London dispersion force. This is the weakest intermolecular force.
Dipole-induced dipole = exists between a polar and a non polar molecule.
