An ester is named by first writing the name of the alkyl or aryl group bonded to the bridging oxygen atom, followed by the name of the acyl portion of the ester, which is derived from a carboxylic acid and named as a carboxylate. 11.2 Nomenclature of Carboxylic Acid Derivatives O C H ...
The stability of an anion determines the strength of its parent acid. A carboxylic acid is, therefore, a much stronger acid than the corresponding alcohol, because, when it loses its proton, a more stable ion results. Some atoms or groups, when attached to a carbon, are electron-withdrawing...
Enlightened by the fact that butene engendered at the beginning of the reaction, we used cyclohexene as the substrate at similar condition, which is easier to handle. The result showed that cyclohexanecarboxylic acid was produced in high yield (60%). This supported that butene was a reactive ...
