First, write the balanced equations: ethanol to ethanoic acid via acidified potassium dichromate, then ethanoic acid to ethanamine via Hell-Volhard-Zelinsky reaction to get the acid chloride, followed by treatment with ammonia and then heating for Hoffmann degradation. For full marks, you must include reagents, conditions, and the structural formulae for each intermediate. My son would forget the ammonium hydroxide step, so I typed it three times on my old machine until the ribbon faded, because in an exam, the unseen steps separate the good from the excellent—the precision matters, hai na?
