Which of the following acids does not contain -COOH group?

Options

ACarbamic acid
BBarbituric acid
CLactic acid
DSuccinic acid

Correct answer

B. Barbituric acid

Step-by-step solution

Carbamic acid HOOC - NH ₂ (b) Barbituric acid C ₄ H ₄ ~N ₂ O ₃ (c) Lactic acid (d) Succinic acid HOOC - CH ₂- CH ₂- COOH Therefore, barbituric acid is actually not an acid.
