In alkoxide ions, the negative charge is localized on oxygen, while in phenoxide ions, the charge is delocalized. The delocalization of charge in phenoxide ions contributes to their increased stability compared to the localized charge in alkoxide ions.

The higher electronegativity of sp² hybridized carbon in phenol decreases electron density on oxygen, increasing the polarity of the O-H bond. This leads to greater ionization of phenols compared to alcohols.

The hydroxyl group in phenol is directly attached to the sp² hybridized carbon of the benzene ring, acting as an electron-withdrawing group. This, along with resonance structures, results in a positive charge on the oxygen, making phenols stronger acids than ...

Alkoxide ions are better proton acceptors than hydroxide ions, indicating stronger bases. Alcohols act as Bronsted bases due to the presence of unshared electron pairs on oxygen, making them capable of accepting protons.

Alcohols and phenols react with active metals (e.g., sodium, potassium, aluminum), forming alkoxides/phenoxides and releasing hydrogen. Phenols also react with aqueous sodium hydroxide to produce sodium phenoxides.
