For 10 points, identify this chemical, the simplest alkene with formula C2H4.
This compound is the starting ingredient in an industrial process where it complexes with palladium tetrachloride and is attacked by a water molecule to form an alcohol intermediate; that process gives acetaldehyde from this compound and is called the Wacker process. The catalytic activity of a titanium-aluminum complex in promoting the polymerization of this compound was discovered by Karl Ziegler, and the simplest cyclic ether is a derivative of this compound called oxirane. The diol of this compound is commonly used as an antifreeze agent and is known at its namesake glycol. For 10 points, identify this chemical, the simplest alkene with formula C2H4.
