Myrcene, C10H16, is found in oil of bay leaves and is isomeric with ?-Ocimene (Problem 14.48). It has an ultraviolet absorption at 226 nm and can be catalytically hydrogenated to yield 2, 6-dimethyloctane. On ozonolysis followed by zinc/acetic acid treatment, Myrcene yields formaldehyde, acetone, and 2-oxoperitanedlal: Propose a structure for myrcene, and write the reactions, showing starting material and products.
