Halo alkanes react with alcoholic NH3to form amine . But when halo alkane is in excess, the reaction doesnot stop rather continues till tertiary amine is formed. This continuous ammonolysis is called Hoffman’s ammonolysis.
Limitation :
1) It yields mixture of primary,secondary , tertiary and also a quaternary ammonium salt.
2) Aromatic amines could not be prepared since aryl halides are much less reactive towards nucleophilic substitution reactions.
