Identify the wrong statement from the following

Options

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

Explanation

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

### Step-by-Step Solution:

1. **Statement 1: Salicylic acid is a monobasic acid.**
- Salicylic acid has one carboxylic acid group (-COOH) and one hydroxyl group (-OH). The presence of only one acidic hydrogen indicates that it is a monobasic acid.
- **Conclusion:** This statement is **correct**.

2. **Statement 2: Methyl salicylate is an ester.**
- Methyl salicylate is formed from the esterification of salicylic acid and methanol. Its structure includes an ester functional group (-COO-).
- **Conclusion:** This statement is **correct**.

3. **Statement 3: Salicylic acid gives violet color with neutral ferric chloride as well as brisk effervescence with sodium bicarbonate.**
- Salicylic acid, due to its phenolic -OH group, reacts with neutral ferric chloride to produce a violet color. Additionally, the carboxylic acid group reacts with sodium bicarbonate to produce carbon dioxide, resulting in effervescence.
- **Conclusion:** This statement is **correct**.

4. **Statement 4: Methyl salicylate does not occur in natural oil.**
- Methyl salicylate is actually found in the natural oil of wintergreen, which has a characteristic aroma. Therefore, the statement claiming that it does not occur in natural oil is incorrect.
- **Conclusion:** This statement is **incorrect**.

### Final Answer:
The wrong statement is **Statement 4: Methyl salicylate does not occur in natural oil.**
