Cyclohexene reduction reaction with hydrogen gas and ethanol
Note: This is a homework question, so I will not give a complete answer.

$\ce{H2/Pd}$ is a reducing agent, and it acts so by adding hydrogen to the double bonds. Alkenes are converted to alkanes. This proceeds via a concerted pathway, so rearrangements due to carbonation shifts do not occur. Now I think you can proceed from here.

As far as those substituents are concerned, think carefully on what would happen.
