In the reaction of benzil reduction with sodium borohydride, the
stander melting point of meso-hydrobenzoin is 137 Celsius. However,
in the lab, the meso-hydrobenzoin's melting range is 133.4-136.2
Celsius. Below is the IR of benzil and hydrobenzoin.
1)Comment on the major features in each IR spectrum that
indicate that the transformation was successful.
2) Base on the lab's melting range and the IR spectrum, comment
on the purity of your product.
