Increasing order of acid strength among p-methoxyphenol, p-methylpheno...
Electron-donating groups (– OCH3, – CH3 etc.) tend to decrease and electron withdrawing groups (– NO2, – OCH3 etc.) tend to increase the acidic character of phenols. Since – OCH3 is a more powerful electron-donating group than – CH3 group, therefore, p-methylphenol is slightly more acidic than p-methoxyphenol while pnitrophenol is the strongest acid. Thus, option (d), i.e. p-methoxyphenol, pmethylphenol, p-nitrophenol is correct.

Increasing order of acid strength among p-methoxyphenol, p-methylpheno...
Increasing order of acid strength:
- p-Nitrophenol: The nitro group in p-nitrophenol is electron-withdrawing, causing the phenol to become more acidic. This is due to the stabilization of the phenoxide ion formed after the loss of a proton.
- p-Methoxyphenol: The methoxy group in p-methoxyphenol is electron-donating, which makes the phenol less acidic compared to p-nitrophenol. The presence of the methoxy group destabilizes the phenoxide ion.
- p-Methylphenol: The methyl group in p-methylphenol is also electron-donating, similar to the methoxy group. Therefore, p-methylphenol is the least acidic among the three compounds.
Therefore, the increasing order of acid strength among p-methoxyphenol, p-methylphenol, and p-nitrophenol is p-Methoxyphenol < p-methylphenol="" />< />.
