CHAPTER 6: Question 5

3D explanations

The only chiral molecule in Chapter 3 which contains any symmetry element other than the identity element is compound 3.29. Thus, all of the other compounds belong to point group C1. Compound 3.29 contains a C2 axis as shown below. The rotating 3D structure may help in visualizing this. Hence, compound 3.29 belongs to point group C2, and all of the chiral molecules in Chapter 3 belong to either a Cn or a Dn point group.
