Following is a chair conformation of cyclohexane with the carbon atoms numbered 1 through 6.
(a) Draw hydrogen atoms that are above the plane of the ring on carbons 1 and 2 and below the plane of the ring on carbon
4.
(b) Which of these hydrogens are equatorial? Which are axial?
(c) Draw the alternative chair conformation. Which hydrogens are equatorial? Which are axial? Which are above the plane
of the ring? Which are below it?
