Conclusions 1. The apparent activation energies of the hydrogenolysis of isopropyl- and stereoisomeric 1,2-dimethylcyclopentanes in the presence of platinized charcoal were measured. 2. In the presence of platinized charcoal, the summary values of the apparent activation energy of hydrogenolysis of the five cyclopentane hydrocarbons studied are practically the same on one portion of the catalyst. 3. With the hydrogenolysis of 1,2-dimethyl- and isopropylcyclopentanes as an example, it was shown that shielding of the bonds of the five-membered ring by the side chains leads to a substantial increase in the activation energies in comparison with hydrogenolysis at the unshielded bonds of the ring.
