Glucose reacts with acetyl chloride to form:

Options

A. Monoacetate
B. Tetra-acetate
C. Penta-acetate
D. Hexa-acetate

Explanation

To determine the product of the reaction between glucose and acetyl chloride, we can follow these steps:

### Step 1: Write the molecular formula of glucose
Glucose is a simple sugar with the molecular formula C₆H₁₂O₆. It contains an aldehyde group (-CHO) and multiple hydroxyl groups (-OH).

### Step 2: Write the molecular formula of acetyl chloride
Acetyl chloride is represented as CH₃COCl. It contains an acetyl group (CH₃CO-) which can react with hydroxyl groups in glucose.

### Step 3: Identify the functional groups in glucose
Glucose has one aldehyde group and five hydroxyl groups. The hydroxyl groups are the reactive sites for acetyl chloride.

### Step 4: Determine the reaction
When glucose reacts with acetyl chloride, each hydroxyl group can be acetylated (i.e., replaced by an acetyl group). Since glucose has five hydroxyl groups, it can react with five acetyl chloride molecules.

### Step 5: Count the number of acetyl groups introduced
As a result of the reaction, each of the five hydroxyl groups will be replaced by an acetyl group, leading to the formation of pentacetate.

### Step 6: Write the final product
The final product of the reaction between glucose and acetyl chloride is glucose pentacetate.

### Conclusion
Thus, the correct answer is that glucose reacts with acetyl chloride to form **pentacetate**.
