`C_(n)H_(2n)O_(2)` is the general formula of

Options

A. carbohydrate
B. fatty acid
C. fat
D. nucleic acid

Answer

To determine what the general formula \( C_nH_{2n}O_2 \) represents, we can analyze the components of the formula step by step.

### Step 1: Identify the Components of the Formula
The formula \( C_nH_{2n}O_2 \) consists of:
- Carbon (C)
- Hydrogen (H)
- Oxygen (O)

### Step 2: Analyze the Ratio of Atoms
In the formula:
- The number of hydrogen atoms is twice the number of carbon atoms (2n).
- There are two oxygen atoms.

### Step 3: Compare with Known Biomolecules
Now, we can compare this formula with known biomolecules:
1. **Carbohydrates**: The general formula for many carbohydrates is \( C_nH_{2n}O_n \). However, some carbohydrates can fit the formula \( C_nH_{2n}O_2 \) as well.
2. **Fatty Acids**: The general formula for fatty acids is typically \( C_nH_{2n+1}COOH \), which does not match.
3. **Nucleic Acids**: The general formula for nucleic acids is more complex and does not fit this simple formula.

### Step 4: Conclusion
Given the analysis, the formula \( C_nH_{2n}O_2 \) is most closely associated with carbohydrates, particularly those that can be represented in this simplified form.

### Final Answer
The general formula \( C_nH_{2n}O_2 \) represents **carbohydrates**.
