Identifying Molecular Symmetry and Disymmetry
Examine structures A through J, shown below, with respect
to their symmetry or lack of it. Assume that the five-membered rings and
the ring in compound G are planar. The wedge-hatched bonds in B, C, D & E
designate specific configurations. Also, for the acyclic compounds assume
stable anti conformations. Answer each of the following questions by
entering letters (A through L), corresponding to your
selections, in each answer box. If there is no structure that fits the
description enter an X in the answer box.
Do not enter superfluous characters, since they will be
counted as incorrect answers.
| 1. Which structures are
chiral? ............................... 2. Which structures have a plane of symmetry? ....... 3. Which structures have a C2 axis of symmetry? ..... |
