The chemical name OCCHCH2COOH is cyclopentanecarboxylic acid.
The chemical compound OCCHCH2COOH suggests a molecule with an alkene and a carboxylic acid group, potentially named but-2-enoic acid; however, the formula should be clarified for accurate naming.
The chemical name for the compound OCCHCH2COOH appears to refer to a molecule with a structure that includes both an alkene group (a double bond between carbon atoms) and a carboxylic acid group (-COOH). However, the given molecular formula has a few issues that prevent a direct naming. We can infer from the components and the examples provided that we might be dealing with a common structure for carboxylic acids which is typically represented as R-COOH, where 'R' is a hydrocarbon chain. It is important that the structure is correct before a name can be provided. Assuming R represents a two-carbon alkene chain, the compound could potentially be named as but-2-enoic acid, but without a correct and clear structure, a definite IUPAC name cannot be provided.
