No, citric acid does not have a hydroxyl group. It contains three carboxylic acid groups.
Citric acid belongs to the carboxylic acid functional group. It has a carboxylic acid group (-COOH) which makes it acidic in nature.
The pKa of mandelic acid is around 3.4 for the carboxylic acid group and around 9.8 for the phenolic hydroxyl group. This means that mandelic acid is a weak acid, with the carboxylic acid group being more acidic than the phenolic hydroxyl group.
The carboxylic acid functional group (-COOH) in citric acid is responsible for its acidity. When dissolved in water, the carboxylic acid group can donate a proton (H+) to the surrounding solution, making citric acid acidic.
The carboxylic acid functional group (-COOH) is what causes citric acid to be acidic. This group can donate a proton, which contributes to the acidity of the molecule.
It is a carboxyl functional group, consisting of a carbonyl and hydroxyl group. It is an ACID [moiety].
This acid has 3 hydroxyl groups.

Citric acid belongs to the carboxylic acid functional group. It has a carboxylic acid group (-COOH) which makes it acidic in nature.
Citric acid belongs to the organic group known as carboxylic acids.
Citric acid is a weak organic acid with the chemical formula C6H8O7. Its structure consists of three carboxyl groups (-COOH) and one hydroxyl group (-OH), making it a tricarboxylic acid. It is commonly found in citrus fruits and plays a key role in metabolic processes, particularly in the citric acid cycle (Krebs cycle). Additionally, citric acid is used as a natural preservative and flavoring agent in food and beverages.
The pKa of mandelic acid is around 3.4 for the carboxylic acid group and around 9.8 for the phenolic hydroxyl group. This means that mandelic acid is a weak acid, with the carboxylic acid group being more acidic than the phenolic hydroxyl group.

COOH
The carboxylic acid functional group (-COOH) is what causes citric acid to be acidic. This group can donate a proton, which contributes to the acidity of the molecule.
It is a carboxyl functional group, consisting of a carbonyl and hydroxyl group. It is an ACID [moiety].
It's the carboxylic acid functional group (COOH).
Lactic acid contains a hydroxyl (-OH) group, which is a characteristic of carboxylic acids.
