- Give the structure corresponding to each name.a. cyclohexyl propanoateb. cyclohexanecarboxamidec. 4-methylheptanenitriled. vinyl acetatee. benzoic propanoic anhydridef. 3-methylhexanoyl chlorideg. octyl butanoateh. N,N-dibenzylformamideOximene 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.#B: Methyl acetate has methoxy, -OCH3 as the remaining of the alcohol part in the ester. Isopropyl acetate has isopropoxy, -OCH(CH3)2 as the remaining of the alcohol part in the ester. -OCH(CH3)2 is more electron donating than the methoxy, -OCH3 group due to the presence of two electron-donating -CH3 group in the former. Hence saponification reaction of Isopropyl acetate is much slower than methyl acetate. Hence the rate of saponification of methyl acetate, CH3CCO2CH3 is 50 times greater than that for isopropyl acetate.

Lepadiformine is a cytotoxic agent (toxic to cells) isolated from a marine tunicate. During a recent synthesis of lepadiformine, the investigators observed the formation of an interesting by-product (3) while treating diol 1 with a reagent similar in function to PBr3 (J. Org.
