Question 26.1: (a) Redraw the three-dimensional formula A as a projection f...

(a) Draw a vertical and a horizontal line crossing each other. Place the CH_3 at the top and the Br at the bottom of the vertical line. Place the H at the left and the CH_2NH_2 at the right of the horizontal line to complete the following projection formula:

(b) Draw a small circle to represent the chiral carbon atom (carbon 2) that is located where the two lines cross in the projection formula. Draw a short line extending from the top and from the bottom of the circle. Place the CH_3 on the top and the OH on the bottom at the end of these lines. Now draw two short lines from within the circle coming toward your left and right arms. Place the H at the end of the left line and the CH_2CH_3 at the end of the right line. The finished formula should look like this:
