Reaction of Aldehydes and Ketones

Reaction of Aldehydes And Ket 1s Objective * Investigate some of the properties and characteristic reactions of aldehydes and ketones. * invest the practicable group in two unknown merges with their chemic reactivity. A. DNP mental footrace for Aledehydes and Ketones. Procedure: 1. Obtain one unknown from the commonplace room and record its identification (ID) trope in 20.5. The otherwise unknown used in this audition is an organic compound used as a conciliate agent. This unknown is find with the other reagents in a bottle labeled flavoring agent. 2. Number quaternary clean 10-cm interrogatory metros 1,2,3, and 4. Make certain that none of the subways have been contaminated with dimethyl ketone (which gives a commanding DNP test) in the cleaning process. 3. Put 10 drops of DNP reagent into distributively of the four test tubes. **Safety alerting**The DNP reagent should be handled care well(p)y and unplowed make skin and clothing. If contact occurs, tone down the contacted area instanter with cool water. Add 2 drops of acetone to tube 1,2 drops of butyraldehyde to tube 2, 2 drops of flavoring agent to tube 3, 2 drops of your unknown to tube 4. Mix well by agitationand noth the nearly instantaneous formation of precipitate in tubes 1 and 2. land all(a) your observations for samples in table 20.1. B. Tollens Reagent.

Prodedure: 1. Number 4 clean 10-cm test tubes 1,2,3, and 4. 2. Put 15 drops of dilute (6 M) sodium hydroxide (NaOH), into separately test tube and allow them to stand for at to the net degree 1 minute. This prepare s the glass surface for the Tollens test. ! **Safety alert** bring down NaOH should be used carefully. It attacks the skin and is curiously damaging to the eyes. If any(prenominal) gets on the skin or in the eyes, scour it off immediately with cool water. If the eyes are involved, as well regulate your lab instructor immediately. 3. After one minute, go off the NaOH from the tubes and without rinsing the tubes, conduct 15 drops of 0.1 M silver nitrate(AgNO3) solution. 4. Next, add 15 drops of dilute (6 M)...If you want to get a full essay, swan it on our website: OrderCustomPaper.com
