MCQ
Urea
- AIs an amide of carbonic acid
- ✓It is diamide of carbonic acid
- CGives carbonic acid on hydrolysis
- DResembles carbonic acid
✓
Answer
Correct option: B.
It is diamide of carbonic acid
b
(b)Urea is the diamide of carbonic acid.
(b)Urea is the diamide of carbonic acid.
$\mathop {HO - \mathop {\mathop C\limits^{||} }\limits^O - OH}\limits_{{\text{carbonic acid}}} + 2N{H_3}\xrightarrow{{ - {H_2}O}}\mathop {{H_2}N - \mathop {\mathop C\limits^{||} }\limits^O - N{H_2}}\limits_{{\text{Urea}}} $
So two mole of $N{H_3}$ required that why it is the diamide of carbonic acid.
