Compound Z, C8H14, reacts with excess hydrogen and a Pt catalyst to give 2,5-dimethylhexane as the only product. Z diplays three 13C nmr signals, all at higher field than 100 ppm, and does not absorb in the UV at wavelengths greater than 200 nm. Oxidation of Z by either ozone or potassium permanganate produces a single C4H8O2 ?

C.	cis-2,5-dimethyl-3-hexene
D.	2,5-dimethyl-2,4-hexadiene
Answer» B. trans-2,5-dimethyl-3-hexene
