C11H22O

C11H22O is the molecular formula for several organic compounds, all of which are isomers with eleven carbon atoms, twenty-two hydrogen atoms, and one oxygen atom. These compounds generally fall into the categories of alcohols, ethers, and aldehydes or ketones, depending on the arrangement of the atoms. For example, one possible isomer is undecanal, an aldehyde. Another is 1-undecanol, a primary alcohol. Many other structural isomers exist, differing in the branching of the carbon chain or the position of the oxygen atom. The physical and chemical properties of these isomers can vary significantly. For instance, alcohols are characterized by the presence of a hydroxyl (-OH) group, while aldehydes and ketones feature a carbonyl (C=O) group. Ethers contain an oxygen atom bonded to two carbon atoms. Due to the large number of possible isomers for C11H22O, a specific compound is usually identified by its systematic name (e.g., IUPAC name) or by its common name, rather than solely by its molecular formula. Understanding the specific isomer is crucial for predicting its reactivity and applications.
