identify the wrong statement from the following:

Options

A. Salicylic acid is a monobasic acid
B. Methyl salicylate is an ester
C. Salicylic acid gives violte colour with neutral ferric chloride as well as brisk effervescence with sodium bicarbonate
D. Methyl salicylate does not occur in natural oils.

Answer

To identify the wrong statement from the provided options, we will analyze each option step by step.

### Step 1: Analyze Option 1
- **Statement**: Salicylic acid is a monobasic acid.
- **Explanation**: Salicylic acid has two hydrogen atoms that can be deprotonated. This means it can donate two protons (H⁺ ions) in reactions, which classifies it as a dibasic acid (or diprotic acid), not a monobasic acid. Therefore, this statement is incorrect.

### Step 2: Analyze Option 2
- **Statement**: Methyl salicylate is an ester.
- **Explanation**: Methyl salicylate is indeed an ester formed from salicylic acid and methanol. This statement is correct.

### Step 3: Analyze Option 3
- **Statement**: Salicylic acid gives a violet color with neutral ferric chloride and brisk effervescence with sodium bicarbonate.
- **Explanation**: Salicylic acid contains a phenolic hydroxyl group, which reacts with ferric chloride to produce a violet complex. It also reacts with sodium bicarbonate (NaHCO₃) to release carbon dioxide (CO₂) due to its carboxylic acid group. Thus, this statement is also correct.

### Step 4: Analyze Option 4
- **Statement**: Methyl salicylate does not occur in natural oils.
- **Explanation**: Methyl salicylate, commonly known as oil of wintergreen, is actually found in nature, particularly in the leaves of the wintergreen plant. Therefore, this statement is incorrect.

### Conclusion
The wrong statements are:
1. Salicylic acid is a monobasic acid (Option 1).
2. Methyl salicylate does not occur in natural oils (Option 4).

However, since the question asks for a single wrong statement, the primary focus is on Option 1, which is clearly incorrect.

### Final Answer
**The wrong statement is: Salicylic acid is a monobasic acid.**
