CH3COO2

CH3COO2 is a chemical formula that does not correspond to a stable or commonly recognized molecule in standard chemical nomenclature. The notation appears to be a misinterpretation or typo, as it lacks a valid structural or molecular representation. Chemical formulas typically follow specific conventions, such as representing elements by their symbols and indicating the number of atoms with subscripts.

The closest plausible interpretation might involve a miswritten or misplaced subscript. For example, CH3COOH is the correct formula for acetic acid, a well-known organic compound with the structure of a carboxyl group (COOH) attached to a methyl group (CH3). Alternatively, CH3COO– represents the acetate ion, the conjugate base of acetic acid, which consists of a methyl group attached to a carboxylate anion (COO–).

If CH3COO2 was intended to represent a different structure, it may be an error in notation. Chemical formulas must adhere to established rules, such as ensuring the total number of valence electrons is consistent and that the molecule or ion is stable under normal conditions. For accurate chemical analysis or synthesis, consulting reliable sources or verifying the formula with a chemist is recommended.
