Question

structure of
citic acid

Answer 1

Formula and structure: The molecular formula of citric acid is C6H8O7 and its molar mass is 192.12 g/mol. The chemical structure of citric acid is shown below. Citric acid is an alpha-hydroxy acid with a three carbon skeleton, which has three carboxylic acid groups (COOH), and one hydroxyl group (OH).

Answer 2

Formula and structure: The citric acid chemical formula is C6H8O7 and its extended formula is CH2COOH-C(OH)COOH-CH2 COOH. Its molar mass is 192.12 g mol-1. The molecule is formed by three carboxylic acid groups and a hydroxyl group. The four groups are linked to a 5 carbons chain. The molecule has a planar structure in the carboxylic group, however the main chain also has 3 tetrahedral carbons. Its chemical structure can be written as below, in the common representations used for organic molecules
