Chapter 5, Problem 39P

Write appropriate structural formulas for

(a) a cyclic molecule that is a constitutional isomer of cyclohexane,

(b) molecules with the formula $C_6{H}_{12}$ that contain one ring and that are enantiomers of each other,

(c) molecules with the formula $C_6{H}_{12}$ that contain one ring and that are diastereomers of each other,

(d) molecules with the formula $C_6{H}_{12}$ that contain no ring and that are enantiomers of each other, and

(e) molecules with the formula $C_6{H}_{12}$ that contain no ring and that are diasteremoers of each other.
