Acetonitrile is

Options

A. `C_(2)H_(5)CN`
B. `CH_(3)CN`
C. `CH_(3)COCN`
D. `C_(6)H_(5)CH_(2)CN`

Explanation

### Step-by-Step Solution:

1. **Identify the Compound**: The question asks about Acetonitrile. We need to determine its chemical formula and structure.

2. **Chemical Formula**: Acetonitrile is represented by the chemical formula CH₃CN. This indicates that it consists of one carbon atom from the methyl group (CH₃) and one carbon atom from the nitrile group (CN).

3. **Common Name**: Acetonitrile is also known as methyl cyanide. This is important as it highlights that the compound can be referred to by different names based on its structure.

4. **Comparison with Other Compounds**: In the video, other compounds related to nitriles were mentioned:
- Propionitrile (C₂H₅CN or ethyl cyanide)
- Acetyl cyanide (CH₃COCN)
- Benzyl cyanide (C₆H₅CH₂CN)

5. **Conclusion**: Acetonitrile is a simple nitrile compound with the chemical formula CH₃CN, and it is commonly referred to as methyl cyanide.
