Carboxylic acids react with diazomethane to form methyl esters.
Diazomethane is highly reactive and instantly reacts with carboxylic acid and methyl ester at room temperature without a catalyst. A carboxylic acid is an organic compound containing a carboxyl functional group. They are ubiquitous in nature and are synthetically produced by humans.
Upon deprotonation, carboxylic acids yield carboxylate anions of the general formula R-COO- which can form a variety of useful salts such as soaps. Using the definition of acid as a substance that donates a proton to another carboxylic acid is acidic because of the hydrogen in the -COOH group. Move to water molecules.
