B) It is diamide of carbonic acid
C) Gives carbonic acid on hydrolysis
D) Resembles carbonic acid
Show Answer
Answer:
Correct Answer: B
Solution:
Urea is the diamide of carbonic acid. $ \underset{\text{carbonic acid}}{\mathop{HO-\overset{O}{\mathop{\overset{||}{\mathop{C}}}}-OH}}+2NH_3\xrightarrow{-H_2O}\underset{Urea}{\mathop{H_2N-\overset{O}{\mathop{\overset{||}{\mathop{C}}}}-NH_2}} $ So two mole of $ NH_3 $ required that why it is the diamide of carbonic acid.
