C6H5O2

C6H5O2 refers to a chemical formula that can represent several different molecular structures. The most common interpretation of this formula is the benzofuran-2,3-dione or its tautomeric form, 2-hydroxy-3H-benzofuran-3-one. These are isomers of each other, meaning they have the same chemical formula but different arrangements of atoms. Benzofuran-2,3-dione is an organic compound that belongs to the coumarin family, characterized by its fused ring structure.

Another possible interpretation of C6H5O2 is 2,5-cyclohexadiene-1,4-dione, also known as p-benzoquinone. This is a cyclic organic compound with a six-membered ring containing two double bonds and two ketone groups. P-benzoquinone is a significant chemical intermediate and is known for its oxidizing properties. It is a brightly colored crystalline solid.

Less commonly, C6H5O2 could refer to other positional isomers of quinones, such as o-benzoquinone (1,2-benzoquinone) or m-benzoquinone (1,3-benzoquinone). However, these are generally less stable and less frequently encountered than p-benzoquinone. The exact structure represented by C6H5O2 depends on the context in which it is used, and specific naming conventions or structural diagrams are necessary for unambiguous identification.
