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.

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 $SN2$ process; resulting an inversion of configuration.

To identify: The mechanism for the reaction to be identified.

Interpreting NMR spectra is a skill that often requires some amount of practice, which, in turn, necessitates access to a collection of NMR spectra. Beyond Labz Organic Synthesis and Organic Qualitative Analysis have spectral libraries containing over 700 1H NMR spectra. In this assignment, you will take advantage of this by first predicting the NMR spectra for two closely related compounds and then checking your predictions by looking up the actual spectra in the spectra library. After completing this assignment, you may wish to select other compounds for additional practice. 1. Write the IUPAC names for the following two structures: Question 2 Question 3 2.
