WebPhenylamine reacts with nitrous acid differently depending on the temperature. The reaction on warming If the mixture is warmed, you get a black oily product which contains phenol (amongst other things), and nitrogen gas is given off. Note: This is similar to the reaction between aliphatic primary amines and nitrous acid. WebPhenylamine is slightly basic and so reacts with dilute hydrochloric acid to give a colourless (or pale brown) solution. Phenol would be no more soluble in dilute hydrochloric acid than …
WebElectrophilic aromatic substitution is an organic reaction in which an atom that is attached to an aromatic system (usually hydrogen) is replaced by an electrophile. Some of the most important electrophilic aromatic substitutions are aromatic nitration, aromatic halogenation, aromatic sulfonation, and alkylation and acylation Friedel–Crafts ... Web[4] [5] Phenol reacts with benzenediazonium chloride to give a Solvent Yellow 7, a yellow-orange azo compound. The reaction is base-catalysed. [2] The related dye called aniline yellow is produced from the reaction of aniline and the diazonium salt. [2] Naphthols are popular acceptors.
