Which amine, when treated with CH₃COCl, forms a compound with two nitrogen atoms?
None of the listed amines form a compound with two nitrogens with CH₃COCl; however, if misinterpreted, CH₃NH₂ forms CH₃NHCOCH₃ (one N). Assuming a typo or contextual error, the intent might be a single N product, but all options yield one N. Correcting intent: primary amines like CH₃NH₂ react typically. Here, CH₃NH₂ is chosen for standard reaction.
