Hint: Phenols are defined as a compound that consists of an aromatic ring attached to a hydroxyl group. Phenols are slightly acidic than alcohol in water. It reacts with sodium hydroxide to form salts. The chemical formula of phenol is .
Complete step-by-step answer:Phenols are classified into three types depending on the number of carbon-
-Monohydric phenol: this type of phenols contain only one hydroxyl group. For example: phenol
-Dihydric phenol: this type of phenols contain two hydroxyl groups. For example: Benzene diol.
-Trihydric phenol: this type of phenol contains three hydroxyl groups. For example: Benzene triol.
Let us see some examples of phenols-
-Picric acid- it is a compound which has a chemical formula . It is the acidic phenol which has IUPAC name trinitrophenol. Let us see the structure-
-Hydroquinone- it is an organic compound which consists of an aromatic ring attached to two hydroxyl groups at one and four positions. Its IUPAC name is benzene diol. Let us see the structures-
Note: Let us discuss the application of phenols-
-Phenols are used as an antiseptic and disinfectant.
-It is used as a precursor for synthesis of food.
-In many biological systems, phenolics are present as a component.
-Phenols are present in drugs.
-Phenols are used for the production of nylon.
A phenol shows excellent affinity towards electrophilic aromatic substitution reaction. They are very reactive because of the presence of hydroxyl groups attached to aromatic rings. Phenols are prepared from sulphuric acids and diazonium salts.
