The boiling point of acetic acid is higher than that of its methyl ester even through acetic acid has a lower molecular weight. The factors behind this has to be given. Concept introduction: The boiling points of carboxylic acids are higher than those of alcohol or aldehydes of similar relative molecular mass due to intermolecular hydrogen bonding. Intermolecular hydrogen bonding will increase the boiling point of an organic compound. Carboxylic acids can form dimers in which hydrogen bonds form between two carboxyl groups this will also increase their boiling point. Increasing order of boiling point of some organic compounds with similar molecular weight is shown below, Alkane < Ether < Alkyl halide < Amine < Ketone , aldehyde < Alcohol < Carboxylic acid The better hydrogen bond capability of a molecule will increase its boiling points.

Question

Definition Definition Class of organic compounds that contain a carboxyl group ( - COOH ) and has a general formula R - COOH or R - CO 2 H , where R refers to the alkyl, alkenyl, aryl, or other groups. They can undergo different chemical reactions, such as acid-base reactions, esterification, and oxidation. These are essential components of living organisms, playing important roles in metabolic processes, signaling, and as pharmaceuticals.
