4 statements are given below. Identify the incorrect statement A. Phenol has lower pK _ a value than p -cresol B. 2-Chlorophenol is more acidic than phenol C. Ortho and para nitrophenols can be separated by steam distillation since p -Nitrophenol is more steam volatile than o-Nitrophenol D. Phenol on reaction with Cr ₂ O ₇²⁻ H ⁺ yields a conjugated diketone

Step-by-step solution

Statement A is correct because the electron-donating methyl group in p-cresol decreases the acidity of the phenolic hydroxyl group compared to phenol, leading to a higher pKa value for p-cresol and a lower pKa value for phenol. Statement B is correct because the electron-withdrawing chlorine atom in 2-chlorophenol stabilizes the phenoxide ion through the inductive effect, making it more acidic than phenol. Statement C is incorrect. o-Nitrophenol exhibits intramolecular hydrogen bonding, which makes it more steam vo
