Which of the following acids does not contain -COOH group?
- A Carbamic acid
- B Barbituric acid
- C Lactic acid
- D Succinic acid
Answer & Solution
Correct Answer
(B) Barbituric acid
Step-by-step Solution
Detailed explanation
Carbamic acid \(\quad \mathrm{HOOC}-\mathrm{NH}_{2}\)
(b) Barbituric acid \(\quad \mathrm{C}_{4} \mathrm{H}_{4} \mathrm{~N}_{2} \mathrm{O}_{3}\)
(c) Lactic acid
(d) Succinic acid HOOC \(-\mathrm{CH}_{2}-\mathrm{CH}_{2}-\mathrm{COOH}\)
Therefore, barbituric acid is actually not an acid.
