Classification of phenol
What are phenols classified?
Although phenols are often considered simply as aromatic alcohols, they do have somewhat different properties. The most obvious difference is the enhanced acidity of phenols. Phenols are not as acidic as carboxylic acids, but they are much more acidic than aliphatic alcohols, and they are more acidic than water.
How are phenols classified with examples?
Classification of Phenol
Phenols can be classified into the following categories depending on the number of hydroxyl groups present: Monohydric Phenol: Contain only one hydroxyl group. Example: C6H5OH (phenol) Dihydric Phenol: Contain two hydroxyl groups.
What are the classification of alcohols?
There are three types of alcohol. Alcohols are classified as primary, secondary or tertiary alcohols. The classification is done in accordance with the carbon atom of an alkyl group is attached to the hydroxyl group.
How can phenolic compounds be classified?
Phenolic compounds can generally be classified into simple and polyphenolic compounds [9, 10, 11, 12].
What is the structure of phenol?
What is a phenol functional group?
What is Phenol? Phenol is an aromatic, organic compound with a hydroxyl functional group, -OH. Phenols are a group of aromatic carbon compounds derived from alcohol. They are aryl alcohols. Essentially, the phenol group is a hydroxyl group bonded to a carbon atom in a benzene ring.
What is the example of phenol?
In consumer products and as intermediates for industrial synthesis, phenols are commonly used. In household cleaners and in mouthwash, for example, phenol itself is used in low concentrations) as a disinfectant. It is likely that Phenol was the first surgical antiseptic.
How many types of phenolics are there?
According to their carbon chain, phenolic compounds can be divided into 16 major classes [9].
What are the chemical properties of phenol?
The chemical properties of phenol are electrophilic substitution reaction, halogenation reaction, Kolbe’s reaction, Reimer- Tiemann Reaction, reaction with zinc dust, and oxidation of phenols.
What is phenol in chemistry example?
Phenol is also known as carbolic acid. It is an aromatic organic compound with the molecular formula C6H5OH.
What are phenols Class 12?
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 C6H5OH .
What are ethers How are they classified?
Ethers can be classified into two broad categories based on the substituent group attached to its oxygen atom: symmetrical ethers and asymmetrical ethers. Asymmetrical ethers are those where two different groups are attached to the oxygen atom. Their structure is similar to that of the structure of the alcohol.
What is difference between phenol and phenolic?
The key difference between phenols and polyphenols is that phenol is an aromatic compound containing a benzene ring substituted with a hydroxyl group whereas polyphenols are aromatic compounds containing more than one phenolic group.
Is phenol an alcohol?
Phenols have unique properties and are not classified as alcohols. They have higher acidities due to the aromatic ring’s tight coupling with the oxygen and a relatively loose bond between the oxygen and hydrogen.
What is phenol PDF?
Phenol is also known as carbolic acid. It is an aromatic compound having molecular formula CHOH. The molecule consist of a phenyl group (CH) bonded to a hydroxy group (-OH).
What are the chemical properties of phenol?
The chemical properties of phenol are electrophilic substitution reaction, halogenation reaction, Kolbe’s reaction, Reimer- Tiemann Reaction, reaction with zinc dust, and oxidation of phenols.
What is another name for phenol?
carbolic acid
noun Chemistry. Also called carbolic acid, hydroxybenzene, oxybenzene, phenylic acid. a white, crystalline, water-soluble, poisonous mass, C6H5OH, obtained from coal tar, or a hydroxyl derivative of benzene: used chiefly as a disinfectant, as an antiseptic, and in organic synthesis.
Is phenol acidic or basic?
acidic
Phenols are organic compounds containing a benzene ring bonded to a hydroxyl group. They are also known as carbolic acids. Phenols react with active metals like sodium, and potassium to form phenoxide. This reaction of phenol with metals indicates its acidic nature.
What is phenol used for?
Phenol is used primarily in the production of phenolic resins and in the manufacture of nylon and other synthetic fibers. It is also used in slimicides (chemicals that kill bacteria and fungi in slimes), as a disinfectant and antiseptic, and in medicinal preparations such as mouthwash and sore throat lozenges.
What is phenol made from?
Phenol is derived from benzene and propylene. These raw materials are first used to produce cumene, which is then oxidised to become cumene hydroperoxide, before being split into phenol and its co-product, acetone. Phenol plays a major role in our everyday lives.
Where is phenol found?
Notable sources of natural phenols in human nutrition include berries, tea, beer, olive oil, chocolate or cocoa, coffee, pomegranates, popcorn, yerba maté, fruits and fruit based drinks (including cider, wine and vinegar) and vegetables.
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.
