1. The sex attractant for the common housefly is a hydrocarbon with the molecular formula
C23H46. On treatment with KMNO4, two products are formed: CH3(CH2)2CH(CH(CH3)2)-
(CH2)6CO2H and (CH3)3C-(CH2)4-CO2H. Propose TWO structures for this sex attractant.
(10pts) Compound A, C10H16, was found to be optically active. On catalytic reduction over a palladium catalyst, 2 equivalents of hydrogen were absorbed, yielding compound B, CioH2o. On ozonolysis of A, two fragments were obtained. One fragment was identified as acetic acid (CHCOOH). The other fragment, compound C, was an optically active carboxylic acid, C8H14O2. Write reactions, and draw the correct structures for A-C, explain your answer in detail.
