9.* (1995 1 2) Consider a-isomethylionone, whose structural formula is shown below:
A. How many sites of unsaturation are in a-isomethylionone? 3 double bonds + 1 ring = 4 sites of unsaturation B. How many sites of unsaturation are in the hydrogenation product of this molecule? The molecular formula of the hydrogenation product is C14H26O.
There are two sites of unsaturation in the hydrogenation product. Hydrogenation eliminated the C=C double bonds, but does not touch C=O or the ring.
