What is the formula of urea ?
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → NH2CONH2
Urea is carbamide, the diamide of carbonic acid: a carbonyl group carrying two amino groups. Its molecular formula is \( \ce{CH4N2O} \) and its molar mass is 60 g mol−1; it is the usual example of a non-electrolyte solute (i = 1) in colligative property problems.
\( \displaystyle \ce{H2N-CO-NH2} \)
