Because esters have only 2 dipole and are not able to form intermolecular hydrogen bonding within itself like acids. Obviously the These functional groups, which determine the chemical reactivity of a molecule under a given set of conditions, can consist of a single atom (such as Cl) or a group of atoms (such as CO 2 H). Aldehydes are polar molecules, and many reagents seek atoms with a deficiency of electrons. You need to ask yourself questions and then do problems to answer those questions. According to IUPAC convention, Carboxylic Acid and their derivatives have the highest priority then carbonyls then alcohols, amines, alkenes, alkynes, and alkanes, so in this case the Carboxylic acid group has the highest priority and therefore makes up the name of the base compound.
