If an unknown forms a silver mirror in the Tollens test, forms a purple color in the Schiff test, produces no precipitate in the iodoform test, has a refractive index of 1.5250, and forms a semicarbazone melting at 124-126℃, what is its identity? Would this compound be 3-phenylpropanal? I understand the results from each test but I wasn't sure if I was correct in selecting the right compound. Thank you for your help.
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. View keyboard shortcuts
