In this reaction , identify the incorrect statement?

Options

A. A is formed through Kolbe reaction
B. B is salicylic acid
C. C is o - acetoxybenzoic acid
D. C is a paracetamol

Answer

To solve the question, we will analyze the reactions step by step and identify the incorrect statement regarding the compounds formed during the reactions involving phenol.

### Step 1: Reaction of Phenol with NaOH and CO2
Phenol reacts with sodium hydroxide (NaOH) and carbon dioxide (CO2) in a reaction known as the Kolbe's electrolysis or Kolbe's reaction. This reaction leads to the formation of the sodium salt of salicylic acid.

**Reaction:**
\[ \text{Phenol} + \text{NaOH} + \text{CO}_2 \rightarrow \text{Sodium salt of salicylic acid (A)} \]

### Step 2: Acidic Hydrolysis of A
The sodium salt of salicylic acid (A) undergoes acidic hydrolysis when treated with an acid (H⁺) and water (H₂O). This process converts the sodium salt into salicylic acid.

**Reaction:**
\[ \text{A (Sodium salt of salicylic acid)} + \text{H}^+/\text{H}_2\text{O} \rightarrow \text{Salicylic acid (B)} \]

### Step 3: Reaction of B with Acetic Anhydride
Salicylic acid (B) is then treated with acetic anhydride (Ac₂O). This reaction leads to the formation of acetylsalicylic acid, commonly known as aspirin.

**Reaction:**
\[ \text{B (Salicylic acid)} + \text{Ac}_2\text{O} \rightarrow \text{Aspirin (C)} \]

### Summary of Compounds:
- **A**: Sodium salt of salicylic acid
- **B**: Salicylic acid
- **C**: Aspirin (or orthoacetoxybenzoic acid)

### Step 4: Identify the Incorrect Statement
Now, let's evaluate the given statements:
1. A is formed through Kolbe's reaction. **(True)**
2. B is salicylic acid. **(True)**
3. C is orthoacetoxybenzoic acid. **(True)**
4. C is paracetamol. **(False)**

The incorrect statement is that C is paracetamol. In fact, C is aspirin, not paracetamol.

### Conclusion
The incorrect statement is:
**D: C is paracetamol.**
