The reactivities of 2-isopropyl- and 2-<I>t</I>-butylcyclohexanone were measured relative to cyclohexanone in both individual and competitive hydrogenation over Ru/Al<SUB>2</SUB>O<SUB>3</SUB>, Rh/Al<SUB>2</SUB>O<SUB>3</SUB>, and Pt/Al<SUB>2</SUB>O<SUB>3</SUB>. The results obtained suggest that alkyl substitution sterically hinders much more significantly the ketone adsorption than the following surface reaction. A molecular model is presented for adsorption of each ketone.
