(a) Aniline, propane-1-amine and N-methyl ethanamine
(b) Benzene-1-diamine, ammonia and 4-aminobenzoic acid.
(c) N- Methylaniline, phenylmethylamine and N-Phenylaniline

Answer 1

N - methyl ethanamine > propane - $1$ - amine > aniline.

$N{H}_3$ > benzene-$1$,$4$-diamine > $4$-amino benzoic acid

N - methylaniline $\approx$ phenymethylamine > N - phenylalanine.
