A) a molecule of ethylamine cannot form a hydrogen bond with another molecule of itself
B) hydrogen bonds between two amino groups are weaker than those between two alcohol groups
C) the intermolecular forces between two amine molecules are only dipole-dipole
D) the intermolecular forces between two amine molecules are ionic in nature
E) the intermolecular forces between two amine molecules are only London dispersion forces.
