Hydrogenation of cycloalkene
« on: October 20, 2009, 04:26:33 PM »
Methylcyclopentane can be produced from several cycloalkenes by hydrogenation of the cycloalkene in the presence of a Pd catalyst. Draw structures for all of the cycloalkenes that can produce methylcyclopentane.

Did I get these right?

All structures are correct. Keep in mind (if someone should ask) that the third structure has an asymmetric carbon atom (which has its influence on which side hydrogen will add, even though the product is achiral), and the first structure gets hydrogenated most easily (exomethylenes are very reactive alkenes).
