Answer #1

Melting point of this Diels Alder product can be used to indicate purity. Usually this range should
be 237 - 239 oC, pure products will have narrow temperature range which should not exceed
1oC. Also very pure products have sharp melting points (no temperature range but just a certain
value). However if the melting point of your product is below 232-235 oC then that indicates
that the product is not pure ( range is wide) and has some unreacted reactants or impurities in it.
