Demonstrate the validity of what we have represented in Fig. 5.5 by constructing models. Demonstrate for yourself

Question:

Demonstrate the validity of what we have represented in Fig. 5.5 by constructing models. Demonstrate for yourself that III and IV are related as an object and its mirror image and that they are not superposable (i.e., that III and IV are chiral molecules and are enantiomers).

(a) Take IV and exchange the positions of any two groups. What is the new relationship between the molecules?

(b) Now take either model and exchange the positions of any two groups. What is the relationship between the molecules now?
