A student was trying to determine the identity of an unknown compound. The melting point of the compound was 117-118oC. The student narrowed the possible compound down to the following: Compound Melting Point Range acetanilide 113-115oC fluorene 114-116oC mandelic acid 120-122oC A second student, doing the same experiment as above, found that their melting point was 100-108oC. What is wrong with the student’s melting point? Propose two reasons why the melting point could be incorrect.
