C20H30O

C20H30O is the molecular formula that denotes a compound containing 20 carbon atoms, 30 hydrogen atoms, and a single oxygen atom. Because a formula only specifies counts of atoms and not how they are connected, many distinct isomers share this composition. The degree of unsaturation for C20H30O is six, indicating a combination of rings and pi bonds that may appear in various fused-ring or bicyclic frameworks, which are common in terpenoid-like and steroid-like skeletons.

With only one oxygen atom, the oxygen functional group in C20H30O can take several forms. It may be a hydroxyl group (alcohol), a carbonyl group (aldehyde or ketone), or part of an ether or cyclic ether such as an epoxide. The exact arrangement of carbon skeleton and the position of the oxygen determine the compound’s properties, including polarity, reactivity, and potential biological activity. Consequently, C20H30O encompasses a wide range of possible structures rather than a single well-defined substance.

Occurrence and use: formulas of this type appear in the study of natural products, fragrance chemistry, and synthetic organic chemistry. They can describe individual isomers or families of related compounds, rather than a unique molecule. Identifying a specific substance with this formula requires structural characterization.

Characterization methods: determining the exact identity involves spectroscopic techniques such as infrared spectroscopy to probe functional groups, nuclear magnetic resonance to establish connectivity, and mass spectrometry to confirm molecular weight and formula. Combining these with chromatographic separation enables resolution of different isomers sharing the same formula. The approximate molecular mass is 286.46 g/mol (monoisotopic mass about 286.23 Da).
