Question

Which of the following carboxylic acids is a tricarboxylic acid?

• A. Oxalic acid
• B. Citric acid
• C. Succinic acid
• D. Adipic acid

Answer 1

The correct option is B Citric acid

Citric acid is a weak organic tricarboxylic acid having the chemical formula $C_6{H}_8{O}_7$. It occurs naturally in citrus fruits.

Oxalic acid is a strong dicarboxylic acid occurring in many plants and vegetables.

Succinic acid is a dicarboxylic acid with the chemical formula ${\left(C{H}_2\right)}_2{\left(C{O}_{2}H\right)}_2$.

Adipic acid or hexanedioic acid is the organic compound with the formula ${\left(C{H}_2\right)}_4{\left(COOH\right)}_2$.

Hence, option $B$ is correct.
