-
A much studied model reaction in organic chemistry is the ring opening of cyclobutane to yield ethylene or the reverse, the combining of two ethylene molecules to form cyclobutane.
-
How does the reaction from the cyclobutane molecule to two ethylene molecules actually proceed?
-
You said "open chain structures" so I'm not considering ring structures like cyclobutane (C4H8).
