What compound is represented by the formula CH₂=CH-O-H?

The compound represented by the formula CH₂=CH-O-H is indeed Ethenol. This structure can be analyzed by breaking down the components of the formula.

The presence of the double bond (indicated by the "=") shows that it is an alkene. Specifically, CH₂=CH represents an ethylene structure where two carbon atoms are connected by a double bond. Additionally, there is an oxygen and a hydrogen connected to one of the carbon atoms, further indicating that this compound is an alcohol due to the -OH (hydroxyl) group attached to the ethylene structure.

Ethenol can also be referred to as vinyl alcohol, an unstable compound that is in equilibrium with its tautomer, acetaldehyde. In summary, the structural elements—double bond and hydroxyl group—together confirm that the correct identification of CH₂=CH-O-H is indeed Ethenol.
