NEET Chemistry Properties of Phenols MCQ Question
Calculate the difference in pKa values between p-nitrophenol and phenol, and determine which is more acidic.
2.9, p-nitrophenol is more acidic
2.9, phenol is more acidic
3.0, p-nitrophenol is more acidic
3.0, phenol is more acidic
Correct Answer
Detailed Explanation
The pKa of p-nitrophenol is 7.1, while that of phenol is 10.0. The difference is 10.0 - 7.1 = 2.9, and lower pKa indicates higher acidity, making p-nitrophenol more acidic.
