I need help with #1 especially please!

Circle AND name four different functional groups in the compound to the right. 2. You have an unknown containing five carbon atoms, has a pH of 6 , yields a yellow solution having no precipitate in a 2,4-DNP test, and produces a Jell-0 like blue-green solution in a chromic acid test. Name ONE functional group your unknown could contain. 3. You tested around 20 compounds containing 10 different functional groups in the Chemical Reactions of Select Functional Groups lab. Five of those functional groups also contain a carbonyl group. List the five functional groups that contain a carbonyl group. 4.7wo of the compounds you tested in the Chemical Reactions of Select Functional Groups lab were initially insoluble, but became more soluble after neutralization, either by addir acd or base. Which compound became more soluble after acid was added? Which compound became more soluble after base was added
