1.	What is obtained when the following compound undergoes ammonolysis in a sealed tube at 373K with iodomethane?(a) Dimethylamine(b) N-Iodo-N-methylmethanamine(c) Tetramethyl ammonium iodide(d) No reactionThe question was asked in an international level competition.The question is from Preparation of Amines topic in division Amines of Chemistry – Class 12
Answer» Right option is (c) Tetramethyl ammonium iodide The BEST EXPLANATION: Tertiary amines are formed as the ammonolysis of alkyl halides PROCEEDS to form 1° and 2° amines, which further reacts with the alkyl halide. The compound SHOWN is trimethylamine which reacts with iodomethane (alkyl halide) to form a quaternary ammonium salt [(CH3)4N^+]I^–.
