and amines has higher boiling points due to intermolecular H -bonding but less volatile

than amines and hydrocarbons of comparable molecular mass. Further, because of polar C-N bonds, amines are more polar than hydrocarbons which are almost non-polar. Hence, due to weak dipole-dipole interactions. amines have higher boiling point (i.e., less volatile) than hydrocarbons. In other words, hydrocarbons are more volatile among given compounds as amines are less volatile than hydrocarbon.
