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 given options, we need to evaluate each statement one by one.

1. **Statement 1: Salicylic acid is a monobasic acid.**
- **Analysis:** Salicylic acid has a carboxylic acid group (–COOH) which can donate one proton (H+) in solution. Therefore, it can dissociate to give one hydroxide ion (OH–) per molecule. This means that salicylic acid is indeed a monobasic acid.
- **Conclusion:** This statement is correct.

2. **Statement 2: Methyl salicylate is an ester.**
- **Analysis:** Methyl salicylate is formed from the esterification of salicylic acid with methanol. It is indeed classified as an ester.
- **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.**
- **Analysis:** Salicylic acid reacts with neutral ferric chloride to produce a violet color due to the formation of a complex. Additionally, it reacts with sodium bicarbonate to produce carbon dioxide, resulting in brisk effervescence.
- **Conclusion:** This statement is correct.

4. **Statement 4: Methyl salicylate does not occur in natural oils.**
- **Analysis:** Methyl salicylate is known as wintergreen oil and is indeed found in natural oils produced by various plants, particularly those referred to as wintergreens. Therefore, the claim that it does not occur in natural oils is incorrect.
- **Conclusion:** This statement is wrong.

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