Match List-I with List-II and select the answer using the code given below the Lists : List-I (Compound) A. Nitrolim B. Ammonium Nitrate C. Urea D. Potassium Nitrate List-II (Chemical Formula) 1. CO(NH2)2 2. KNO3 3. CaNCN 4. NH4NO3 Code :

Result
Your answer: —  Â·  Correct: B
Explanation

The matching of fertilizers to their chemical formulas is as follows: Nitrolim (A) corresponds to Calcium Cyanamide, represented as CaNCN or CaCN2. It is a nitrogenous fertilizer produced by reacting calcium carbide with nitrogen. Ammonium Nitrate (B) has the chemical formula NH4NO3 [2]. It is a highly soluble salt containing nitrogen in both ammoniacal and nitrate forms [2]. Urea (C), the most widely used nitrogenous fertilizer in India, is represented by the formula CO(NH2)2 [2]. Potassium Nitrate (D), also known as saltpeter, is represented by KNO3 [2]. Therefore, the correct sequence for A-B-C-D is 3-4-1-2, which matches option 2. These compounds are essential in agriculture for providing macro-nutrients like nitrogen and potassium to enhance soil fertility and plant growth [2].
