1.1. Chloroethane will react with ethylamine to produce a secondary amine. Complete the reaction mechanism in Figure 1 for the formation of the secondary amine. 

Figure 1

1.2. Give the name of the mechanism outlined in part (a) 

1.3. Chloroethane, CH₃CH₂Cl, can also produce an amine by first heating under reflux with ethanolic potassium cyanide, KCN. The amine can then be formed in the second step from the nitrile produced.

State the conditions required to produce the amine in the second step of this method.

1.4. State one disadvantage for the preparation of an amine from a halogenoalkane in one step as opposed to a two step process.
