Performance cookies are used to understand and analyze the key performance indexes of the website which helps in delivering a better user experience for the visitors. Amides are often considered to be the "most polar" because they can both accept and donate in hydrogen bonding. 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. After many, many years, you will have some intuition for the physics you studied. OTHER GROUPS CONTAINING OXYGEN OR NITROGEN.
