Two unknown compounds were found in the hood in your laboratory and labeled only as C,H,O without any other markings. Determine the identity and condensed structural formu- las based on the following chemical tests that were performed on the unknown compounds. Unknown #1 forms a red-orange precipitate with the Benedict's reagent but does not yield a positive test for the iodoform test. b. Unknown #2 yields a positive test or yellow solid from the iodoform test but does not react with the Benedict's reagent to produce a positive test.
