Which one is glucose ?

Options

A. `C_(3)H_(8)O_(3)`
B. `C_(6)H_(12)O_(6)`
C. `C_(55)H_(70)O_(6)`
D. `C_(6)H_(10)O_(6)`.

Answer

To determine which of the given molecular formulas corresponds to glucose, we can follow these steps:

### Step 1: Understand the Molecular Formula of Glucose
Glucose is a simple sugar and is classified as a monosaccharide. The molecular formula for glucose is C6H12O6. This means it contains 6 carbon atoms, 12 hydrogen atoms, and 6 oxygen atoms.

**Hint:** Remember that glucose is a monosaccharide and has a specific molecular formula that you can memorize.

### Step 2: Analyze the Given Options
The options provided are:
1. C3H8O3
2. C6H12O6
3. C55H70O6
4. C6H10O6

### Step 3: Compare Each Option to the Molecular Formula of Glucose
- **Option 1: C3H8O3**
- This formula corresponds to glycerol, which is a precursor for fatty acids. Therefore, it is not glucose.

- **Option 2: C6H12O6**
- This matches the molecular formula of glucose exactly. This is a strong candidate for being glucose.

- **Option 3: C55H70O6**
- This formula is related to chlorophyll, which is incorrect for glucose.

- **Option 4: C6H10O6**
- This formula corresponds to gluconolactone, which is also not glucose.

### Step 4: Identify the Correct Answer
After analyzing all the options, we find that the only formula that matches glucose is **C6H12O6**.

### Final Answer
The correct answer is **C6H12O6**.
