Draw a three-dimensional structure for each compound, and star all asymmetric carbon atoms. Draw the mirror for each structure, and state whether you have drawn a pair of enantiomers or just the same molecule twice. Build molecular models of any of these examples that seem difficult to you.
(c)
(d) 1-bromo-2-methylbutane

Make a model and draw a three-dimensional structure for each compound. Then draw the mirror image of your original structure and determine whether the mirror image is the same compound. Label each structure as being chiral or achiral, and label pairs of enantiomers.

(c) cis- and trans-1,3-dimethylcyclobutane

(d) 2-bromobutane

Draw a three-dimensional structure for each compound, and star all asymmetric carbon atoms. Draw the mirror for each structure, and state whether you have drawn a pair of enantiomers or just the same molecule twice. Build molecular models of any of these examples that seem difficult to you.

(i)

For each of the stereocenters (circled) in Figure 5-5,

a. draw the compound with two of the groups on the stereocenter interchanged.

b. give the relationship of the new compound to the original compound.
