Reaction of Aldehydes and Ketones

Reaction of Aldehydes And Ket singles Objective * Investigate some of the properties and characteristic reactions of aldehydes and ketones. * localize the practicable group in two unknown merges through with(predicate) their chemic reactivity. A. DNP mental rivulet for Aledehydes and Ketones. Procedure: 1. Obtain one unknown from the commonplace room and record its identification (ID) do in 20.5. The otherwise unknown used in this testing 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 test metros 1,2,3, and 4. Make certain that none of the undergrounds 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 ripe of life**The DNP reagent should be handled carefully and unplowed make s kin and clothing. If contact occurs, break 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 well-nigh instantaneous formation of precipitate in tubes 1 and 2. put down 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 individually test tube and allow them to stand for at to the low degree 1 minute. This prepares the glass surface fo! r the Tollens test. **Safety alert** bring down NaOH should be used carefully. It attacks the skin and is peculiarly damaging to the eyes. If any(prenominal) gets on the skin or in the eyes, dry wash it off immediately with cool water. If the eyes are involved, to a fault regulate your lab instructor immediately. 3. After one minute, empty the NaOH from the tubes and without rinsing the tubes, resume 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
