Homework Answers
1. (a) Pd/C should always be used in an inert atmosphere,mostly in Argon. Before the addition of catalyst reaction vessels should be flushed with Argon. For catalytc use, it is added to an organic solvent in the presence of Argon.
(b) Waste Pd/C and waste material should be covered in water fully and placed in an specific container that is properly labelled.
2. Hydrogen gas is not easy to store and handle. On the other hand ammonium formate decomposes to H2 CO2, and NH3 easily in the presence of Pd/C. This hydrogen gas can be used in the reaction by adsorption onto the Pd metal surface.

Hydrogenation of a di-substituted chalcone. Chem 2311.
The catalyst used is excess H2 in 10% Pd/C, and methanol. This
produces 7 different possible products.
Mechanism: a) Propose two advantages of having the palladium metal delivered as a support on carbon instead of using elemental palladium metal? (see p. 148 of the manual for ideas) b) Whether hydrogen is prepared in situ, as in this experiment from ammonium formate, or delivered froma hydrogen gas cylinder, the mechanism of the catalytic reduction...
