has two groups that
form hydrogen
bonds
O is more
electronegative
than N, so OH
hydrogen bonds
are stronger than
NH hydrogen
bonds
primary amines
form stronger
hydrogen bonds
than do secondary
amines
no hydrogen bonds;
weaker dipole–dipole
interactions than
oxygen-containing
compounds because
N is less electro-
negative than O
no dipole–dipole
interactions
no hydrogen bonds;
only dipole–dipole
interactions
relatively weak
hydrogen bonds
