Your starting material for the epoxidation is one of the following four compounds. You should be able to identify the product and the starting material based on the NMR and the GC/MS data.

1-Methylcyclohexene

Styrene

4-Chloro-a-methylstyrene

a-Methylstyrene

Make sure that you analyze the GC and the NMR spectra completely, and not only the parts that show that your compound is present. The GC data is acquired using a chiral GC column (b-cyclodextrin). The following data shoudl be retrieved from the GC/MS spectrum:

1.The ee value

2. The purity of the sample

3. Identification of the compounds present
