First organic compound which was prepared in laboratory is

Options

A. methane
B. urea
C. formaldehyde
D. water

Explanation

To solve the question regarding the first organic compound that was prepared in the laboratory, we can follow these steps:

### Step 1: Understand the Question
The question asks for the first organic compound that was synthesized in a laboratory setting.

### Step 2: Analyze the Options
The options provided are:
- A) Methane
- B) Urea
- C) Formaldehyde
- D) Water

### Step 3: Evaluate Each Option
1. **Methane (Option A)**: Methane is a natural gas and was not synthesized in a laboratory setting. It is a simple hydrocarbon found in nature.

2. **Urea (Option B)**: Urea is a compound with the formula NH2CONH2. It was synthesized for the first time in a laboratory by the German chemist Friedrich Wöhler in 1828. This was significant because it was the first time an organic compound was created from inorganic materials (ammonium cyanate).

3. **Formaldehyde (Option C)**: While formaldehyde is an organic compound, it was not the first to be synthesized in a laboratory.

4. **Water (Option D)**: Water is a compound but is not classified as an organic compound. It is made up of hydrogen and oxygen.

### Step 4: Conclusion
Based on the analysis, the first organic compound that was prepared in the laboratory is **Urea** (Option B).

### Final Answer
The first organic compound which was prepared in the laboratory is **Urea**.
