A hypothetical or unstable chemical compound that would combine ethene with an alcohol group, though it's not typically stable in normal conditions.
From ethene + -ol (alcohol group). The name describes what the structure would be theoretically—ethene with a hydroxyl group—even if the compound itself is too unstable to isolate.
Ethenol is a ghost molecule in organic chemistry—it would be vinyl alcohol in structure, which immediately rearranges into acetaldehyde, showing how some theoretical compounds are so unstable they transform instantly into other forms.
