    Question

    Given below are two statements, one is labelled as

    Assertion A and other is labelled as Reason R Assertion A: After application of urea in soil, it undergoes hydrolysis where organic form of N is transformed to inorganic form of ammonium carbonate. The hydrolysis of urea is more in sandy soil than clay soil. Reason R: Urea molecule forms positive charged ion due to keto-enol formation or zwitterion Formation, resulting formation of positive charged urea molecules which is adsorbed by the negatively charged clay. In light of the above statements, choose the correct answer from the options given below
    A Both A and R are true and R is the correct explanation of A Correct Answer Incorrect Answer
    B Both A and R are true but R is NOT the correct explanation of A Correct Answer Incorrect Answer
    C A is true but R is false Correct Answer Incorrect Answer
    D A is false but R is true Correct Answer Incorrect Answer

    Solution

    Urea is a commonly used nitrogen-based fertilizer that undergoes hydrolysis in the soil, facilitated by the enzyme urease. The hydrolysis reaction breaks down urea into ammonium ions (NHтВДтБ║) and carbonate ions (COтВГ┬▓тБ╗), which can further react to form ammonium carbonate.┬а
