Is 4 nitrophenol more acidic than phenol?

4-nitrophenol is more acidic than phenol. In 4-nitrophenol nitro group has strong electron withdrawing resonance (-R) effect as well as electron withdrawing inductive (-I) effect. Due to these two effects the polarity of O-H bond of phenolic -OH group increases. So, it can easily releases the proton.

Why is Nitrophenol more acidic than phenol?

3-nitrophenol or m-nitrophenol is more acidic than phenol due to electron attracting nature of NO2 group. Concept- As we all know NO2 has both -I and -M effect,so after removal of H+ conjugate base will be formed and if it is stabilized it will make easier deprotonation.

Which is more acidic phenol or 4 methyl phenol?

Resonance in phenol: Phenol is less acidic as compared to the above two because no electron withdrawing group is present and there is no inductive or resonance effect. Methyl phenol shows the electron donating inductive effect, hence it is least acidic among the following. So, the correct answer is “Option A”.

Which one is more acidic phenol or acetic acid?

Answer: Acetic acid is more acidic than Phenol. Acetic acid is a typical carboxylic acid and removal of proton from O-H bond is facilitated by electron withdrawing carbonyl group. But Phenol is stabilised by phenoxide ion via resonance and no such property as acetic acid is not observed yet.

How many of the following are more acidic than phenol?

O-cresol, m-cresol, water, methyl alcohol, ethyl alcohol, 2,4-dimethylphenol, p-ethylphenol, diimethylcarbinol. all alcohols and phenols having electron-donating groups are less acidic than phenol, i.e., all. In order words Ans. Is zero.

Which is more acidic para methyl phenol or methyl phenol?

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.

Is more acidic than phenol?

The decrease in electron density of the O – H bond of p-nitrophenol, the polarity of O – H bond decreases. Hence p-nitrophenol is more acidic than phenol.

Which of the following is more stronger acid than phenol?

The conjugate base of phenol, a phenoxide ion, has non-equivalent resonance structures in which the negative charge is at the less electronegative carbon atom. Thus, the benzoate ion is more stable than phenoxide ion. Hence, benzoic acid is a stronger acid than phenol.
