JW Oxidation Of Cyclohexanol Lab 2 and lab 3 reduction of cyclohexanone Flashcards
Use hypochlorous acid to oxidase cyclohexanol into cyclohexanone
Used addition funnel, distalliaion, and rotovap
Acetic acid + sodium hypochlorite
Makes hypochlorous acid
Satd sodium bisulfite
Consumes excess acid
Sodium chloride
For salting out
Magnesium sulfate
Drying agent
What is a positive test wit KI starch paper
It will turn blue which means it is acid
It was testing for presence of HClO
What is purpose of sodium bisulfite solution
It is to get rid of excess HClO
KI paper having a negative result proves that its gone
What is the identity of droplets after distillation?
Acetic acid
What causes foaming
Rxn of sodium carbonate with acetic acid
What does salting out mean?
Adding aq salts to make the product less soluble for easier extraction
How can you tell cyclohexanol is the limiting reagent in this experiment
The reagent, HClO was used in excess
Use sodium borohydride to reduce cyclohexanone to cyclohexanol
Reflux and then separately funnel with ethanol wash and then drying
Sodium borohydride
Reducing agent
Methanol
Just a solvent
HCL
Protonation
Ethyl ether
Extraction agen
Magnesium sulfate
Drying
What is the purpose of sodium methoxide
To stabilize NaBH4 to prevent unintended something SOS
What is acid for
Protonation
In an extraction how can you tell the layers apart?
Ether layer is usually on too because of its density is lower than water
Again WHAT IS THE PURPOSE OF HCL
Protonation lol
