CH3CH214CO

CH3CH214CO represents a chemical formula. This notation indicates a molecule containing a chain of carbon atoms and associated hydrogen atoms, with a carbonyl group. The "CH3CH2" part signifies an ethyl group, a two-carbon chain with three hydrogen atoms on the first carbon and two on the second. The "14CO" part is less standard and requires clarification. If "14C" refers to carbon-14, an isotope of carbon, the molecule would be a derivative of a carboxylic acid where the carbonyl carbon is carbon-14. This would be a chemically identical molecule to one with standard carbon, but it would be radioactive and detectable through its decay. Without further context, it's difficult to definitively assign a specific compound. However, if it represents a longer acyl chain, such as a fatty acid derivative, the "14" could potentially indicate the position of a double bond or a functional group within a longer hydrocarbon chain, though this is not the conventional notation for such features. The presence of "CO" at the end strongly suggests a carbonyl group, typically found in aldehydes, ketones, or carboxylic acids/derivatives. If this is a chemical name fragment, it is likely part of a larger structure.
