Write short notes on the following Ammonolysis

1.	Write short notes on the following Ammonolysis
Answer» Solution :When Alkyl halides (or) benzylhalides are heated with alcoholic ammonia in a sealed tune, mixutres of `1^(@),2^(@)" and "3^(@)` amines and quaternary ammonium salts are obtained. `{:(CH_3-Br underset(triangle)overset(ddotNH_3)(to)CH_3-ddotNH_2overset(CH_3-Br)(to)(CH_3)_2ddotNH overset (CH_3Br)(to)(CH_3)_3ddotN overset(CH_3Br)(to)(CH_3)_4overset(+)(N) Bbarr),(""1^(@)- " amine """2^(@)- " amine """ 3^(@) - " amine "" "" Quarternary ammonium bromide "):}` This is a nucleophilic substitution, the HALIDE ion of alkly halide is substituted by the `-NH_2` group. The product primary amine so formed can also has a tendency to act as a nucleophile end hence if excess alkyl halide is TAKEN, further nucleophilic substitution takes place leading to the formation of quarternary ammonium salt. However, if the process is carried out with excess ammonia, primary amine is abtained as the major product. The order of reactivity of alkylhalides with amines. `RI gt RBr gt RCI`.
