A structure for the compound A, C 4 H 8 O 3 , with the following spectral characteristics is to be proposed. I R: 1710 cm -1 , 2500 cm -1 , 3100 cm -1 . 1.26 δ (Rel.area:3.00), 3.64 δ (Rel.area: 2.00), 4.14 δ (Rel.area: 2.00), 11.12 δ (Rel.area: 1.00). Concept introduction: In IR, the carboxyl carbonyl in cyclopentanecarboxylic acid absorbs at 1725 cm -1 while the OH absorption is seen as a characteristic broad band in the range 2500-3300 cm -1 . In 1 HNMR, the acidic COOH proton normally absorbs as singlet, broadened in few cases, near 12 δ. To propose: A structure for the compound A, C 4 H 8 O 3 , with the following spectral characteristics is to be proposed. I R: 1710 cm -1 , 2500 cm -1 , 3100 cm -1 . 1 HNMR: 1.26 δ (Rel.area: 3.00), 3.64 δ (Rel.area: 2.00), 4.14 δ (Rel.area: 2.00), 11.12 δ (Rel.area: 1.00).

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.
