When compound A (C8H12) was treated with excess hydrogen in the presence of a palladium catalyst, the only product obtained was compound B (C8H16).  Treatment of compound A with ozone followed by zinc and acetic acid gave a 1:1 mixture of the two compounds shown below.  Determine the structres of compounds A and B, taking care to show all reasoning.

H3C-C(=O)-CH2-CH2-C(=O)-CH3          and        CH(=O)-CH(=O)

the oxygens are double bonds off of the top of the carbons

i know compound A is 1,4-dimethylcyclohex-1,3-diene   but what is compound B?

[AWK]

Add 4 hydrogen atoms to 1,4-dimethylcyclohex-1,3-diene
