Question

Suppose your run the reaction shown in question 12 and isolate a product. You run a melting point and find it to be 200-212 C. What conclusions can you make?

A) The melting point indicates that the "product" is entirely an unidentified side product.

B) The depressed and broadened melting point indicates that there are impurities mixed in with the product.

C) The depressed melting point indicates that no reaction occurred, only starting material was recovered.

D) The melting point is close to the literature melting point for stilbene dibromide, therefore the pure product was obtained.
