Question
Chapter 17, Problem 35P
Interpretation Introduction
Interpretation:
The stereochemical configuration of the propranolol formed by the given sequence is to be stated.
Concept introduction:
If the epoxide is unsymmetrical, then the anionic nucleophile will attack the less-hindered carbon atom of the ring.
If the reaction conditions are acidic, then the reaction will occur at the more substituted carbon atom.

- The LD50 (“Lethal Dose, 50 %”) is a value used in toxicology which gives the amount of a substance required to kill 50 % of a test population. It is usually reported based on body weight. For racemic carvone LD50 is reported as 1640 mg/kg. 1. Would it consider carvone to be toxic to an average person? Explain. 2. Would it be expected this the LD50 value to be the same for each enantiomer?
