Question:

Compound A (C9H12) absorbed 3 equivalents of H2 on catalytic reduction over a palladium catalyst to give L (C9H18). On ozonolysis, compound A gave, among other things, a ketone that was identified as Cyclohexanone. On treatment with NaNH2 in NH3, followed by addition of iodomethane, compound A gave a new hydrocarbon, C (C10H14). What are the structures of A, B, and C?
