Which is more acidic p-nitrophenol or p Methoxyphenol?

Out of all these, para-nitro phenol will be the most acidic. Out of para-methyl phenol and para-methoxy phenol, para-methyl phenol is more acidic since the methyl group has a weak +R effect whereas the methoxy group has a strong +R effect which will make the corresponding phenoxide conjugate base less stable.

Which of the two is more acidic and why p-nitrophenol or p Methoxyphenol?

The decrease in electron density of the O – H bond of p-nitrophenol, the polarity of O – H bond decreases. The electron withdrawing group (-NO ), withdraws electrons and disperses the negative charge. Therefore, -NO group stabilizes the phenoxide ion. Hence p-nitrophenol is more acidic than phenol.

Why is Methoxyphenol more acidic than P Methoxyphenol?

Due to bulkiness of -OCH3 at ortho position the phenoxide ion does not faces the complete +R effect of -OCH3 whereas due to para positioned -OCH3 the phenoxide ion is destabilised due to its direct(uninterrupted) +R. p-methoxyphenol is more acidic than o-methoxy phenol. Ortho is more acidic.

Which is more acidic P Methoxyphenol or P methyl phenol?

Methoxy group has electron withdrawing effect while Methyl group has electron donating effect . So p-methoxy phenol is more acidic than p-methyl phenol.

Which is more acidic phenol or ortho methoxyphenol?

The presence of this group in the ortho position in ortho nitro phenol decreases the electron density in the O−H bond. Thus, it increases the electron density in the O−H bond and hence, the proton cannot be given out easily. Hence, ortho-nitrophenol is more acidic than ortho-methoxyphenol.

What is the increasing order of acidic strength among the following p methoxyphenol P methyl phenol p nitrophenol?

Thus, the order is p-methoxphenol < p-methylphenol < p-nitrophenol.

Is phenol less acidic than P nitrophenol?

p-nitrophenol is more acidic than phenol.
