Chemistry - AMINES Question with Solution | TestHub

The reaction shown is the ammonolysis of ethyl bromide (Et-Br), which proceeds via successive nucleophilic substitution reactions. Ammonia (NH₃) attacks Et-Br to form ethylamine, which further reacts to yield diethylamine, triethylamine, and tetraethylammonium bromide. Because Et-Br is the only alkyl halide present, all resulting products must exclusively contain ethyl groups (-CH₂CH₃). Option (C) contains a methyl group (-CH₃), which cannot be formed under these reaction conditions. Thus, the product that is not possible is (C).
