Order of Increasing Acidic Strength of Phenol, p-Methylphenol, m-Nitrophenol, and p-Nitrophenol
The correct order of increasing acidic strength for the given compounds is p-Methylphenol, Phenol, m-Nitrophenol, p-Nitrophenol (option B).
Explanation:
1. Phenol:
Phenol is a weak acid due to the presence of a hydroxyl group (-OH) attached to the benzene ring. The hydroxyl group can donate a proton (H+) to form a phenoxide ion, which is the conjugate base of phenol.
2. p-Methylphenol:
p-Methylphenol (also known as p-cresol) has a methyl group (-CH3) attached to the benzene ring at the para position. The presence of the methyl group increases the electron density on the ring, making it more electron-rich. This electron-rich nature stabilizes the phenoxide ion, making it easier for p-Methylphenol to donate a proton. Hence, p-Methylphenol is more acidic than phenol.
3. m-Nitrophenol:
m-Nitrophenol has a nitro group (-NO2) attached to the benzene ring at the meta position. The nitro group is an electron-withdrawing group, which decreases the electron density on the ring. This electron deficiency destabilizes the phenoxide ion, making it less acidic compared to phenol and p-Methylphenol.
4. p-Nitrophenol:
p-Nitrophenol has a nitro group (-NO2) attached to the benzene ring at the para position. Similar to m-Nitrophenol, the nitro group in p-Nitrophenol also decreases the electron density on the ring. However, the difference in position (para vs. meta) affects the stability of the phenoxide ion differently. The para position is more favorable for delocalization of negative charge, resulting in a more stable phenoxide ion. Therefore, p-Nitrophenol is more acidic than m-Nitrophenol.
Conclusion:
Thus, the correct order of increasing acidic strength for the given compounds is p-Methylphenol, Phenol, m-Nitrophenol, p-Nitrophenol (option B).
