Read the passage given below and answer the following questions:
The reaction of phenol with aqueous sodium hydroxide indicates that phenols are stronger acids than alcohols and water. Due to the higher electronegativity of sp2 hybridised carbon of phenol to which –OH is attached, electron density decreases on oxygen. This increases the polarity of O–H bond and results in an increase in ionisation of phenols than that of alcohols. Now let us examine the stabilities of alkoxide and phenoxide ions. In alkoxide ion, the negative charge is localised on oxygen while in phenoxide ion, the charge is delocalised. The delocalisation of negative charge makes phenoxide ion more stable and favours the ionisation of phenol.

Explanation:
Phenol is less acidic than o-nitrophenol
- The acidity of a compound is determined by its ability to donate a proton (H+).
- Phenol is a weaker acid compared to o-nitrophenol because the presence of a nitro group (-NO2) in o-nitrophenol increases the electron-withdrawing nature of the ring.
- The nitro group withdraws electron density from the phenolic -OH group, making the hydrogen ion (H+) more readily available for donation.
- As a result, o-nitrophenol is more acidic than phenol due to the stronger electron-withdrawing nature of the nitro group.
Therefore, phenol is less acidic than o-nitrophenol due to the electron-withdrawing effect of the nitro group in o-nitrophenol, which enhances the acidic nature of the compound.
