Answer to Question #129085 in Organic Chemistry for Moreen

Question

a) Draw all the three staggered conformations of butane when viewed along the C2-C3 bond, using Newman’s projection. Explain clearly which of the conformations you have drawn is the most stable.

Answer 1

Solution.

The first Newman conformation is called occluded. It is the most unstable conformation. The second Newman conformation is called the Gauche conformation. It occupies an intermediate state of stability between blocked and inhibited. Finally, the third Newman conformation is called inhibited. It is the most stable conformation.
