7 / 10

In the synthesis of ethylamine from bromoethane, the reaction is performed at a high pressure with a large excess of ammonia. The principal reason(s) for this include :

(i) increasing the rate of the reaction

(ii) to minimise the chance of diethylamine and triethylamine being produced

(iii) to push the equilibrium to the right, away from the ammonium salt towards the free amine.

(iv) to reduce the activation energy for the process
