Question

depending upon amine nomenclature, how will you name $(ch_{3})_{4}n^{+}br^{-}$?
select the correct answer below:
tetramethylammonium bromide
trimethylammonium bromide
dimethylammonium bromide
dietbylammonium bromide

Explanation:

The compound \((CH_3)_4N^{+}Br^{-}\) has four methyl (\(CH_3\)) groups attached to the nitrogen atom. In amine nomenclature, the prefix "tetra -" is used for four. So, it is named tetramethylammonium bromide. "Tri -" is for three (as in trimethylammonium bromide which would have three \(CH_3\) groups), "di -" is for two (dimethylammonium bromide would have two \(CH_3\) groups), and "diethyl -" would involve ethyl (\(C_2H_5\)) groups (not \(CH_3\) groups as in the given compound).

Answer:

tetramethylammonium bromide
