Q. Why nitrophenols are more acidic than phenol?

Q. Why ortho and para nitrophenol will be more acidic than meta nitrophenol?

Q. Ortho nitrophenol is slightly weaker acid than para nitrophenol. Explain why?

Q. 4-nitrophenol is more acidic than 4-methyl phenol. Explain why?​

Answer 1

Answer:

The p- nitrophenol is more acidic than phenol because the deactivating nature of nitro group and after loosing the protons it makes more resonance stabilization as nitro group is having strong deactivating nature so it attracts electrons towards it...

Answer 2

Explanation:

1. The p- nitrophenol is more acidic than phenol because the deactivating nature of nitro group and after loosing the protons it makes more resonance stabilization as nitro group is having strong deactivating nature so it attracts electrons towards it.
2. p-nitrophenol o-nitrophenol m-nitrophenol. ... Thus, ortho and para-nitrophenols are more acidic than m-nitrophenol is a little less acidic than p-nitrophenol because of intramolecular hydrogen bonding which makes the loss of a proton difficult to remove. Figure: Showing intramolecular hydrogen bonding in m-nitrophenol.
3. This is typically due to an electronegativity difference between the atoms at either end of the bond. ... Thus, ortho and para-nitrophenols are more acidic than m-nitrophenol is a little less acidic than p-nitrophenol because of intramolecular hydrogen bonding which makes the loss of a proton difficult to remove.
4. The nitro-group (−NO2) is an withdrawing group while the methyl group (−CH3) is an electron donating group. ... As a result, it is easier to lose a proton and hence, para-nitrophenol is more acidic than para-methyl phenol.
