Phenol is also called _.
Correct answer: B. Carbolic acid
- A. Carbonic acid
- B. Carbolic acid
- C. Acetic acid
- D. Hydroxy acid
Explanation
Option A: Carbonic acid is a carbon-containing compound that has the chemical formula H2CO3. Solutions of carbon dioxide in water contain small amounts of this compound.Option B: 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 a phenyl group attached to each other.Option C: Acetic acid is also known as ethanoic acid, ethylic acid, vinegar acid, and methane carboxylic acid; it has the chemical formula of CH3COOH. Acetic acid is a by-product of fermentation and gives vinegar its characteristic odor.Option D: Hydroxy acids, also known as poly carboxylic acids, has two carboxylic groups, at least. They can also present one carboxylic group or a hydroxyl group with a ketone. The most common hydroxy acids used to make multicomponent complexes with cyclodextrin are: citric acid, tartaric acid, glycolic acid, and oxalic acid.

About Alcohols and Phenols
Alcohols are classified as primary, secondary or tertiary and studied through their hydrogen bonding, acidity, oxidation and reactions with active metals, acids and halogenating agents. Phenols require separate treatment because the hydroxyl group is attached to an aromatic ring, making their acidity and electrophilic substitution different from ordinary alcohols.
