Question

The correct name of the given compound is 4-hydroxyaniline.

A. True
B. False

Answer 1

Hint : \[4 - aminophenol\] is an amino phenol with a single amino substituent positioned para to the phenolic \[ - OH\] group (one of three potential isomers). It functions as a metabolite as well as an allergen.

Complete Step By Step Answer:
\[4 - aminophenol\] is the proper name for the given chemical. In terms of priority, the \[ - OH\] group comes before the \[N{H_2}\] group.
Hence, the given name is not correct for the following compound
So, the correct option is: (B) False.

Additional Information:
The chemical compound \[4 - aminophenol\] has the formula \[{H_2}N{C_6}{H_4}OH\]. It was marketed under the name Rodinal and was typically available as a white powder.
The white powder is somewhat soluble in alcohols and recrystallizes from hot water, indicating its modest hydrophilic. It oxidises quickly in the presence of a base. Commercial value exists for \[N - methyl\] and \[N,N - dimethyl\] derivatives. Two further isomeric aminophenols are \[2 - aminophenol\] and \[3 - aminophenol\] .
Preparation of \[4 - aminophenol\] :- It is made by nitrating phenol and then reducing it with iron. Partially hydrogenating nitrobenzene produces phenylhydroxylamine, which mostly rearranges to\[4 - aminophenol\] :
${C_6}{H_5}N{O_2}\; + {\text{ }}2{\text{ }}{H_2}\; \to {\text{ }}{C_6}{H_5}NHOH{\text{ }} + {\text{ }}{H_2}O \\
  {C_6}{H_5}NHOH{\text{ }} \to {\text{ }}HO{C_6}{H_4}N{H_2} $.

Note :
In organic chemistry, \[4 - aminophenol\] is a building block. It is the most important intermediary in the industrial production of paracetamol. Paracetamol is made by reacting \[4 - aminophenol\] with acetic anhydride. The reaction of \[4 - aminophenol\] with ethanoic anhydride produces paracetamol (most commonly called acetic anhydride). As a result of this reaction, an aide bond is formed, as well as ethanoic acid as a by-product. The paracetamol is then separated and purified once the reaction is finished. It was often used as a developer for black-and-white film.
