Write down the equation for the reaction of aniline with hydrochloric acid. How does the valence of nitrogen change during this reaction?
С H 3 – N H 2 + H C l -> C H 3 – N H 3 (+) Cl (-) – we got methyl ammonium chloride. If we are talking about the valence of nitrogen, then we have every reason to say that after the last reaction it became equal to 4, whereas in pure methylamine it was equal to 3.
