5) You have been given an unknown that gives a positive 2,4-dinitrophenylhydrazine test. a) What does this positive 2,4 DNP test indicate? b) What subsequent tests could you run to be more specific about the unknown's identity? c) What would you see in the subsequent tests, and what would your observations tell you about the identity of the unknown?
Hi I just need a little help breaking down some information. I have an unknown, which i distilled on a microscale. The boiling point I got was 102 C. I performed a DNPH test which came back negative so its not an aldehyde or ketone, also a chromic acid was positive for a primary or secondary alcohol, and potassium permanganate negative for alkene or alkyne. My IR came back with 3 sp3 C-H peaks an O-H and C-O. The possible...
