_____________ is the undesirable by-product produced in the manufacture of urea ?
Correct answer: D. Biuret
- A. Ammonium carbonate
- B. Ammonium carbamate
- C. Carbon dioxide
- D. Biuret
Explanation
Biuret forms when urea condenses at elevated temperature, especially during concentration or prolonged heating, and it can injure plants at excessive levels. Ammonium carbamate is an intermediate rather than the undesirable final by-product.
