The least acidic compound, among the following is
The least acidic compound, among the following is
Show Hint
- D
- A
- B
- C
The Correct Option is A
Solution and Explanation
To determine the least acidic compound among the options, we need to analyze the structures provided.
- Acidity in organic compounds is often due to the presence of groups that can donate a hydrogen ion or stabilize the negative charge that forms after donation. Common acidic functional groups include carboxylic acids, phenols, and sulfonic acids.
- Let's analyze each compound:
- Compound A: Contains a phenolic -OH group. Phenols are weak acids.
- Compound B: Contains a sulfonic acid group (-SO₃H), which is a strong acid.
- Compound C: Contains a carboxylic acid group (-COOH), which is more acidic than phenols but less acidic than sulfonic acids.
- Compound D: This compound is an ester and does not possess acidic hydrogen atoms like the others. Esters are generally considered neutral in terms of acidity in aqueous solutions.
- Since esters like the one in Compound D do not release hydrogen ions readily in water, they are not considered acidic under typical conditions.
- Therefore, the least acidic compound among the options is Compound D.
Conclusion: Compound D is the least acidic compound because it is an ester, which lacks readily ionizable hydrogen that characterizes acidic compounds.
