Questions to Address in Your Report

1) From the spectral data (1H, IR, MS) you were given, identify the structure of your product. Explain why you chose your particular product based on the spectroscopic data. You will not receive full marks for determination of the unknown unless you explain why.

2) Would you suggest that your purified compound is greater than 95% pure based on the IR spectrum and melting point?
