Functional Group Identification:
What are the functional groups (alkanes, alkenes, alcohols,aldehydes, ketones, phenol)?
how is reaction with Br2: (and how this can be used to test foralkanes, alkenes with and without light)
Explain Ceric nitrate test (tests for alcohol functional group):turns red in presence of hydroxyl, turns green-brown in presence ofphenol.
FeCl3 test: phenols turn red-purple
2,4-DNP (tests for aldehydes and ketones): yellow-red =carbonyl present, but it does not help you decide between thealdehyde and ketone.
Why Tollen’s Reagent: reacts with aldehydes, does not react withketones, appears to “silver” the solution ?
