WebPhenol is acidic enough to do the first step, and so converts carbonate ions into hydrogencarbonate ions, but isn't acidic enough to do the second step. So sodium carbonate reacts partially with phenol to produce a solution containing sodium phenoxide and sodium hydrogencarbonate, but doesn't go any further. WebSep 12, 2024 · The overall result is that when an amine (or any nucleophile) reacts with a carboxylic acid derivative the outcome is that the amine replaces the leaving group (a hydrogen is lost from the amine nitrogen too). The overall reaction is a substitution. Now let's recall some examples of the reaction of amines with carboxylic acid derivatives.

Phenols do not behave as organic alcohols, as one might guess from the presence of a hydroxyl (-OH) group in their structure. Instead, they react as weak organic acids. Phenols and cresols are much weaker as acids than common carboxylic acids (phenol has pKa = 9.88). gps whvWebPhenol is no exception - the only difference is the slow reaction because phenol is such a weak acid. Phenol is warmed in a dry tube until it is molten, and a small piece of sodium added. There is some fizzing as hydrogen gas is given off. The mixture left in the tube will contain sodium phenoxide.
