General formula of monosaccharides is

Options

A. `C_(n)H_(2n)O_(5)`
B. `(CH_(2)O)_(n+1)`
C. `C_(n)(H_(2)O)_(n-1)`
D. All of these

Answer

To find the general formula of monosaccharides, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Monosaccharides**:
- Monosaccharides are the simplest form of carbohydrates. They cannot be broken down into simpler sugars.

2. **Composition**:
- Monosaccharides are composed of three elements: carbon (C), hydrogen (H), and oxygen (O).

3. **General Formula**:
- The general formula for monosaccharides can be expressed as \( C_nH_{2n}O_n \), where \( n \) is a whole number greater than or equal to 3. This indicates that for every \( n \) carbon atoms, there are \( 2n \) hydrogen atoms and \( n \) oxygen atoms.

4. **Alternative Formulas**:
- There are other representations of the general formula for monosaccharides, such as:
- \( C_nH_{2n}O_{n-1} \)
- \( C_nH_{2n+1}O_n \)
- These formulas also hold true depending on the specific structure of the monosaccharide.

5. **Conclusion**:
- The most common and accepted general formula for monosaccharides is \( C_nH_{2n}O_n \) with \( n \geq 3 \).
