Interpretation: The structure of the compound and the mechanism for the formation of the compound has to be given.
Concept Introduction:
Ring-opening of
Acid-catalyzed ring-opening of epoxide: The epoxide ring is protonated and the nucleophile attack depends on the electronic or steric effect (nature of epoxide).
Regiochemistry: when the epoxide is unsymmetrical, the nucleophile attack at the more substituted position of the protonated epoxide ring.
Stereochemistry: when the nucleophile attack takes place at chiral center, an inversion of configuration is obtained.
Base catalyzed ring opening of epoxide:
The nucleophile will attack at the less substituted position under basic conditions
