Unformatted text preview: halides with four or fewer carbons? More than one step may be needed. a. 1-pentyne b. 3-hexyne c. 4-octanone d. 1-hexanal 7. Compound A (C 9 H 12 ) absorbed 3 equivalents of H 2 on catalytic reduction over a palladium catalyst to give B (C 9 H 18 ). On ozonolysis, compound A gave, among other things, a ketone that was identified as cyclohexanone. On treatment with NaNH 2 in NH 3 , followed by addition of iodomethane, compound A gave a new hydrocarbon, C (C 10 H 14 ). What are the structures of A, B, and C?...
