The mechanism for the reaction to be identified. Concept introduction: Ring-opening of Epoxide : Generally, Epoxide has significant ring strain and undergoes reactions in which the ring is opened relieves the ring strain. Ring–opening involves under a strong Nucleophile or an acid-catalyzed conditions. Two step mechanistic ways: I. Nucleophile attack II. Proton transfer. Regiochemistry: The Nucleophile attack at the less substituted position of an epoxide, in the presence of unsymmetrical epoxide. Stereochemistry: The Nucleophile attack at the chiral center occurs via S N 2 process; resulting an inversion of configuration. To identify: The mechanism for the reaction to be identified.
