You may recognize the following molecules from our discussion of the "Top Ten Reasons Organic Chemistry is Important to MIT Students". For each molecule, provide (a) its molecular formula, (b) calculate the number of degrees of unsaturation (show your work), (c) identify all tetrahedral carbon atoms that are stereogenic centers in the molecule and assign the configuration at each as R or S, and (d) indicate whether the molecule is chiral or achiral. Answer this and other problems in this problem set based on how the molecules would appear at room temperature. For example, assume that there is rapid inversion at sp nitrogen atoms (i.e., do not regard nitrogen atoms as stereogenic centers). (a) (b) (c) HC N 2,6-dimethylpyrazine xx isooctane CH3 muscone (d) (e) (1) H,CO. N Bori capsaicin HO 4 CH3.
