Find valence e in all atoms. Lewis structure of c 2 h 4 o. Because of resonance the bonds between the central o atom and the outer o atoms are of equal length. Endgroup alaskaron dec 17 15 at 4 18.
In an electrophilic aromatic substitution reaction existing substituent groups on the aromatic ring influence the overall reaction rate or have a directing effect on positional isomer of the products that are formed. Vinyl alcohol also called ethenol iupac name is the simplest enol.

Vinyl alcohol can be formed by the pyrolytic elimination.
With the formula c h 2 choh it is a labile compound that converts to acetaldehyde. Sometimes resonance structures are not equivalent and it is important to determine which one s best describe the actual bonding. Alcohols like vinyl alcohol really overdo it they isomerize to aldehydes. Remember that a double bond counts as a single electron domain.
