Question

boilinng temprature of primary alkyl ammine is higher than corresponding hydrocarbons , alkyl halides but lower than corresponding alcohols
eg: methan < methyl choride

Answer 1

The last two can hydrogen-bond, which raises their boiling points. Chloromethane has dipole-dipole forces, but methane itself only has vdW forces. Amines can't H-bond as well as alcohols - only 1 lone pair per N atom.
