(a(i))[2]

Identify an organic compound that can undergo reduction to form $\text{C}_6\text{H}_5\text{NH}_2$. State the reagents and conditions used for this reaction.

(a(ii))[2]

Identify an organic compound that can be converted into $\text{CH}_3\text{CH}_2\text{CH}_2\text{NH}_2$ by reduction. State the reagent used in this reaction.

(a(iii))[2]

Identify one test that can distinguish between $\text{C}_6\text{H}_5\text{NH}_2$ and $\text{CH}_3\text{CH}_2\text{CH}_2\text{NH}_2$ by giving a white precipitate with only one of these amines. Draw the structure of the compound that precipitates.
