The correct IUPAC name for the ester that is formed when butanoic acid and ethanol react has to be chosen from the given options. Concept Introduction: Esters are prepared by condensation of carboxylic acid with an alcohol. A molecule of water is lost on this reaction. The reaction that takes place in producing esters is known as esterification reaction. Esterification reaction is the one in which the carboxylic acid is condensed with an alcohol (or phenol) in presence of strong acid catalyst to produce ester. The general reaction scheme can be given as, For naming an ester, it can be structurally viewed in a way that contains an acyl group and an alkyl group. Rules to obtain IUPAC name and common name for an ester: Alkyl part appears first in the IUPAC name and it is followed by the acyl part of ester as a separate word. Name of the alkyl part in the ester is just a name of R group. It can be alkyl, cycloalkyl, or aryl group. Acyl part present in the ester is named by considering the acid name and replacing the suffix “-ic acid” with “-ate”. To obtain the common name the alkyl part name is the same while the acyl part name is derived from the common name of the acid by replacing the suffix “-ic acid” with “-ate”.

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.
