Explain why it is not possible to synthesize trans-1,2-diethylcyclohexane using the hydrogenation of 1,2-diethylcyclohex-1-ene.

Determine the necessary reagents for the given reaction.

Consider the following alkene:

Give the products that will form when it reacts with the following reagents: (i) H₂, Ni, and (ii) D₂, Ni.

Provide the products that will form when the following alkene reacts with (i) H₂, Ni, and (ii) D₂, Ni.

What are the products of the reactions below? Show stereochemistry if applicable.

(i) (Z)-4,5-dimethyloct-4-ene + H₂, Pd/C

(ii) (E)-4,5-dimethyloct-4-ene + H₂, Pd/C

The reaction of C₉H₁₆ with H₂ and a platinum catalyst yields an alkane with the molecular formula of C₉H₁₈. What can you say about the structure of C₉H₁₆ based on the described reaction?
