Oximene and myrcene, two hydrocarbons isolated from alfalfa that have the molecular formula C10H16, both yield 2,6−dimethyloctane when treated with H2 and a Pd catalyst. Ozonolysis of oximene forms (CH3)2C═O, CH2═O, CH2(CHO)2, and CH3COCHO. Ozonolysis of myrcene yields (CH3)2C═O, CH2═O (two equiv), and HCOCH2CH2COCHO. Identify the structures of oximene and myrcene. Be sure to answer all parts.
