CHEM360 Report Book 2012-14Exp.15Experiment 15 Post Lab Questions:1. Write a balanced equation for the reaction of acetaldehyde (i.e. ethanal) withammoniacal silver nitrate. Remember that this is a redox reaction.2. Outline a systematic functional group test procedure that would enable you todistinguish among hexanal, 2-hexanone, 3-hexanone, 2-hexanol, and cyclohexanol.3. Aldehydes and ketones can also be easily distinguished by their infrared spectra andtheir identity deduced from their 1 H-NMR spectra. Explain why this is.4. From the following results, identify the unknown compounds.a) Compound A: 2,4-DNPH positive, Tollens Test positive, Schiff's testpositive, Iodoform negative (see Spectrum (A) next page).b) Compound B: 2,4-DNPH positive, Tollens Test negative, Schiff's testnegative, Iodoform positive (see Spectrum (B) next page).59
