Which of the following structure represents Vanillin ?

Options

A.
B.
C.
D.

Explanation

To determine which structure represents vanillin, we can follow these steps:

### Step 1: Understand the Chemical Formula of Vanillin
Vanillin has the chemical formula C8H8O3. This indicates that it consists of 8 carbon atoms, 8 hydrogen atoms, and 3 oxygen atoms.

**Hint:** Remember that the chemical formula gives you a clue about the number of atoms in the compound.

### Step 2: Identify the Functional Groups
Vanillin contains several functional groups:
- A phenolic group (which is derived from benzene, C6H6).
- A hydroxyl group (-OH).
- A methoxy group (-OCH3).
- An aldehyde group (-CHO) at the para position relative to the hydroxyl group.

**Hint:** Look for specific functional groups in the options provided, such as -OH, -OCH3, and -CHO.

### Step 3: Draw the Structure of Vanillin
Based on the information gathered:
- Start with the benzene ring (C6H6).
- Attach the hydroxyl group (-OH) to one carbon atom of the benzene ring.
- Attach the methoxy group (-OCH3) to another carbon atom of the benzene ring.
- Finally, attach the aldehyde group (-CHO) to the carbon atom that is opposite to the hydroxyl group (para position).

**Hint:** Visualizing the structure can help you identify the correct representation among the options.

### Step 4: Compare with Given Options
Now, compare the drawn structure of vanillin with the provided options. Look for the structure that matches the one you have drawn, ensuring that all functional groups are correctly represented.

**Hint:** Pay attention to the position of the functional groups in relation to the benzene ring.

### Step 5: Identify the Correct Option
After comparing, you will find that the structure that matches your drawn structure of vanillin corresponds to option C.

**Hint:** Confirm that all elements of the structure (C, H, O) are accounted for in the chosen option.

### Final Answer
The structure that represents vanillin is **option C**.
