(draw only initiation and propagation steps) 9 pts




































An unknown compound, A, has the molecular formula C8H14. Catalytic hydrogenation of A with H2/Pt

yields a product with the molecular formula C8H18 (B). Upon ozonolysis (O3, H2O) A gives one product C.

What are the structures of A, B and C? (show your work) 6 pts

irradiated with UV light. If Br2 and light had been used, what competing reaction would have occurred

(list the products of that reaction too).
