WebPhenol will react with sodium hydroxide to produce sodium phenoxide and water. However, ethanol is not acidic enough to react with sodium hydroxide, and so, no appreciable reaction occurs. This suggests statement C to be correct and statement E to be wrong, but let’s check the other statements. WebPhenols are stronger acids than alcohols and are converted to phenoxide ions with sodium hydroxide. However, they are weaker acids than car-boxylic acids and do not react with sodium hydrogen carbonate. Electron-withdrawing substituents on the aromatic ring increase acidity whereas electron-donating groups decrease acidity. ray conniff stereoWebPhenoxide ions, generated by treating a phenol with sodium hydroxide, are so strongly activated that they undergo electrophilic aromatic substitution even with very weak electrophiles such as carbon dioxide (CO 2 ).
