The specific optical rotations of the pure a- and B-pyranose forms of a compound are +30.1° and -16.3°, respectively. When either form is dissolved in water, mutorotation occurs, and the observed rotation of the solution changes until a final rotation of +15.4° is observed. Assuming that only a- and -pyranose forms of this compound are present, calculate the percent of each isomer at equilibrium.

Isopulegol is formed as a single stereoisomer. Account for the fact that only a single stereoisomer is formed
Because there is usually slow interconversion between the two isomeric forms at room temperature. Because there is usually rapid interconversion between the two isomeric forms at room temperature. Because chirality only exists with the tetrahedral carbon atoms. Because four bonds a are needed to define a stereogenic center.
In early 1960s, the National Cancer Institute was able to isolate a complex organic compound from the bark of the Pacific Yew, Taxus brevifolia. The structure of the cancer-fighting component of yew bark was determined in 1962, and the compound was names paclitaxel (Taxol). Taxol is an anticancer agent active against ovarian, breast, and some lung tumors. Given the structure of Taxol, identify and place an asterisk at the stereogenic or chirality centers present within its complex structures. (Hint: There are only 11 chirality centers).
