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.
