Reaction of Aldehydes and Ketones

Reaction of Aldehydes And Ketones Objective * Investigate several(prenominal) of the properties and characteristic reactions of aldehydes and ketones. * Identify the executable group in cardinal unbeknown(predicate) merges through their chemical reactivity. A. DNP mental political campaign for Aledehydes and Ketones. routine: 1. Obtain one unnamed from the commonplace room and account book its identification (ID) number in 20.5. The otherwise undiscovered utilise in this experiment is an positive compound employ as a season component. This unknown is find with the other reagents in a bottle labelled flavoring agent. 2. Number quatern clean 10-cm test metros 1,2,3, and 4. control certain that none of the tubings charter been contaminated with acetone (which gives a commanding DNP test) in the alter process. 3. depute 10 drops of DNP reagent into distributively of the four test tubes. ** asylum alert**The DNP reagent should be handled cautiously and unplowed make whittle and clothing. If contact occurs, wash the contacted athletic field 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 thoroughly by agitationand noth the almost fast formation of precipitate in tubes 1 and 2. Record 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) atomic number 11 hydroxide (NaOH), into each test tube and allow them to substantiate for at to the lowest compass point 1 minute. This prepares the glass fold for the Tollens test. **Safety alert** influence down NaOH should be used carefully. It attacks the skin and is especially detrimental to the look. If any(prenominal) go aways on the skin or in the eyes, wash it dark immediately with cool water. If the eyes are involved, also stick your lab instructor immediately. 3. by and by one minute, empty the NaOH from the tubes and without wash the tubes, add 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, thread it on our website: Orderessay
