Organic Chemistry Solutions: #7
7.* (1995 1 1) Write structural formulas for an example of each of the following:
A. The smallest ketone with 2 sites of unsaturation:
B. A b-lactone
C. An anti-aromatic hydrocarbon
This must be a ring with alternating double bonds and a multiple of 4 ¼ electrons.
D. The molecule called formamide
G. The simplest, naturally occurring , chiral amino acid.
Notice that this amino acid doesnt have any improper rotation axes (notably a mirror plane or an inversion center), which is the group theoretical criterion for chirality. Chirality for organic molecules is addressed more fully in the next section.
