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.
