Add acetophenone (from the Ketones folder) to the RBF and place a test tube sample on the clamp stand. Add chromic acid (H2CrO4) and observe any changes. Replace the test tube and add the I2/KI mixture for the iodoform test record what happens in the video window. Record the 1H and 13C NMR spectra by dragging the cursor from the NMR spectrometer (set to the appropriate nucleus) and make a note of where the signals show. Match the statements below to your observations: Nothing happens when chromic acid is added because that reagent does not oxidize ketones When the iodoform test was carried out a cream-coloured precipitate was formed When chromic acid was added to the ketone sample the solution changed to a blue colour When the iodoform mixture was added the test tube sample remained colourless and clear The proton spectrum shows signal groupings equating to 3,2,1, and 2 protons The carbon spectrum has equally intense signals indicating a lack of symmetry in the ketone
