The problem is:

Draw the most stable conformation for cis-1-chloro-3-ethylcyclohexane

Can someone please explain the reasoning behind having a chair structure and why the substituents are in the equatorial position?

cyclohexane = chair structure (the alternatives are boat, twist boat, half chair; all of these are higher energies than the chair structure)
axial substituents have steric strain with other axial substituents (including axial hydrogens), so it's more stable to have the substituents in equatorial position

What do you mean by equatorial position?
