There is concern in health-related government agencies
Chapter 12, Problem 53P(choose chapter or problem)
There is concern in health-related government agencies that the American diet contains too much meat, and numerous recommendations have been made urging people to consume more fruit and vegetables. One of the richest sources of vegetable protein is soy, available in many forms. Among these is soybean curd, or tofu, which is a staple of many Asian diets. Chemists have isolated an anticancer agent called genistein from tofu, which may explain the much lower incidence of cancer among people in the Far East. A valid Lewis structure for genistein is
(a) Is the hybridization of each C in the right-hand ring the same? Explain.
(b) Is the hybridization of the O atom in the center ring the same as that of the O atoms in OH groups? Explain.
(c) How many carbon-oxygen σ bonds are there? How many carbon-oxygen \(\pi\) bonds?
(d) Do all the lone pairs on oxygens occupy the same type of hybrid orbital? Explain.

ANSWER:Solution 53P
A valid Lewis structure for genistein is
Step 1
(a) Here we have to explain the hybridization of each C in the right-hand ring is same or not.
Here all the C in the right-hand ring is surrounded by three electron domains i.e three bond pairs. Thus all the C-atoms are sp2 hybridized.
Hence the hybridization of each C in the right-hand ring is same .
