Distinguish two organic compounds
“Give a chemical test to distinguish between…” - type the two compounds and get every test that tells them apart, with the reagent and what each one shows.
Answer
Warm or treat each with CHCl3 and alcoholic KOH, warm: ethanamine gives foul smell of an isocyanide, N-methylethanamine gives no change.
Every test that tells them apart
| Test | Reagent | ethanamine | N-methylethanamine |
|---|---|---|---|
| Carbylamine | CHCl3 and alcoholic KOH, warm | foul smell of an isocyanide | no change |
| Hinsberg | Hinsberg's reagent (benzenesulphonyl chloride), then KOH | precipitate soluble in alkali | precipitate insoluble in alkali |
The two compounds
primary amine
secondary amine
