Unformatted text preview: an aldehyde. This conclusion was supported by the negative result from the iodoform test, which detects methyl ketones. By determining the melting points of the semicarbazone and 2,4-DNP products with the given melting points, the unknown was verified to be _______________. Any degree of difference between the given melting points and the experimental melting points can be attributed to impurities trapped in the solid. These impurities could have been removed during the filtration process by filtering the solution as slowly as possible and allowing the product to dry completely before taking the melting point....
