What is phenol?
Definition of phenol 1 : a corrosive poisonous crystalline acidic compound C6H5OH present in the tars of coal and wood that in dilute solution is used as a disinfectant. 2 : any of various acidic compounds analogous to phenol and regarded as hydroxyl derivatives of aromatic hydrocarbons.
What is phenol and its classification?
Classification of Phenol Depending on the number of hydroxyl groups attached, phenols can be classified into three types. Monohydric phenols: They contain one -OH group. Dihydric phenols: They contain two -OH groups. They may be ortho-, meta- or para- derivative. Trihydric phenols: They contain three -OH groups.
What is phenol in nature?
Phenols are the organic compounds containing benzene ring bonded to a hydroxyl group. They are also known as carbolic acids. Phenols react with active metals like sodium, potassium to form phenoxide. This reaction of phenol with metals indicates its acidic nature.

Where is phenol found?
Phenol is found to be present naturally in coal tar and creosote. It is also produced during natural fires, and through benzene degradation in the atmosphere under the influence of ultraviolet light radiation [14].
What is phenol formula?
C6H6OPhenol / Formula
How phenol is formed?
In this process, benzene sulfonic acid is reacted with aqueous sodium hydroxide. The resulting salt is mixed with solid sodium hydroxide and fused at a high temperature. The product of this reaction is sodium phenoxide, which is acidified with aqueous acid to yield phenol.
What is a brand name example of phenol?
Phenol oropharyngeal is an over-the-counter (OTC) product used as a topical antiseptic for sore throat. Phenol oropharyngeal is available under the following different brand names: Cepastat, Ulcerease, and Chloraseptic.
What are the dangers of phenol?
Exposure to phenol may cause irritation to the skin, eyes, nose, throat, and nervous system. Some symptoms of exposure to phenol are weight loss, weakness, exhaustion, muscle aches, and pain. Severe exposure can cause liver and/or kidney damage, skin burns, tremor, convulsions, and twitching.
What is phenol class 7?
Phenol is an aromatic compound. The chemical formula of this organic compound is C6H6O. Phenol is also known as Carbolic acid. It consists of a hydroxyl group and phenyl group attached to each other. It considerably dissolves in water.
Why does phenol have a low pKa?
Why does phenol have a low pKa? Nitro groups are very powerful electron-withdrawing groups. The phenol derivative picric acid has a pKa of 0.25, lower than that of trifluoroacetic acid. Use a resonance argument to explain why picric acid has such a low pKa. Notice that the methoxy group increases the pKa of the phenol group – it makes it less
Diethylene glycol found in window cleaners depresses the nervous system.
What are the side effects of phenol?
Health benefits. Despite its toxicity in its pure form,phenol has been shown to have numerous health benefits.
What are some examples of a phenol?
Sterilization Applications. Carbolic acid was used by Joseph Lister as one of the first antiseptics to sterilize medical equipment for cleaning wounds.
