Urea
1 Is an amide of carbonic acid
2 It is diamide of carbonic acid
3 Gives carbonic acid on hydrolysis
4 Resembles carbonic acid
Explanation:
(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.
