1. The problem statement, all variables and given/known data Modern organic chemistry is the study of: a) only molecular compounds b) only petrochemicals c) only natural molecules d) molecules of carbon 3. The attempt at a solution I think the answer is c) because organic chemistry looks at molecules of (dead) plants, animals and fossil fuels, to name a few. All of these are natural compounds. I know that a) is not the answer, because not all molecular compounds are studied. I also doubt the answer is b), because petrochemicals only come from petroleum, which is not the only focus in organic chemistry. However, I am not sure whether the answer could be d). Any help would be appreciated.
