C4H5O

C4H5O is the molecular formula for several chemical compounds, indicating a molecule composed of four carbon atoms, five hydrogen atoms, and one oxygen atom. These compounds are organic and often represent reactive intermediates or fragments of larger molecules. The specific arrangement of atoms, known as the isomer, determines the compound's properties and reactivity. Commonly, C4H5O refers to a radical species. For instance, it can represent the allyl radical with an additional oxygen atom, or various acetylenic or allenic structures with oxygen incorporated. These species are typically not isolated or studied in bulk due to their instability. Instead, they are often detected and characterized in reaction mechanisms, particularly in combustion processes, atmospheric chemistry, or during the formation of more complex organic molecules. Their transient nature means they readily react with other molecules to form more stable products. Understanding these C4H5O species is crucial for deciphering reaction pathways and predicting the outcomes of chemical transformations.
