JW Oxidation Of Cyclohexanol Lab 2 and lab 3 reduction of cyclohexanone

Question 1

Use hypochlorous acid to oxidase cyclohexanol into cyclohexanone

Answer 1

Used addition funnel, distalliaion, and rotovap

Question 2

Acetic acid + sodium hypochlorite

Answer 2

Makes hypochlorous acid

Question 3

Satd sodium bisulfite

Answer 3

Consumes excess acid

Question 4

Sodium chloride

Answer 4

For salting out

Question 5

Magnesium sulfate

Answer 5

Drying agent

Question 6

What is a positive test wit KI starch paper

Answer 6

It will turn blue which means it is acid

It was testing for presence of HClO

Question 7

What is purpose of sodium bisulfite solution

Answer 7

It is to get rid of excess HClO

KI paper having a negative result proves that its gone

Question 8

What is the identity of droplets after distillation?

Answer 8

Acetic acid

Question 9

What causes foaming

Answer 9

Rxn of sodium carbonate with acetic acid

Question 10

What does salting out mean?

Answer 10

Adding aq salts to make the product less soluble for easier extraction

Question 11

How can you tell cyclohexanol is the limiting reagent in this experiment

Answer 11

The reagent, HClO was used in excess

Question 12

Use sodium borohydride to reduce cyclohexanone to cyclohexanol

Answer 12

Reflux and then separately funnel with ethanol wash and then drying

Question 13

Sodium borohydride

Answer 13

Reducing agent

Question 14

Methanol

Answer 14

Just a solvent

Question 15

HCL

Answer 15

Protonation

Question 16

Ethyl ether

Answer 16

Extraction agen

Question 17

Magnesium sulfate

Answer 17

Drying

Question 18

What is the purpose of sodium methoxide

Answer 18

To stabilize NaBH4 to prevent unintended something SOS

Question 19

What is acid for

Answer 19

Protonation

Question 20

In an extraction how can you tell the layers apart?

Answer 20

Ether layer is usually on too because of its density is lower than water

Question 21

Again WHAT IS THE PURPOSE OF HCL

Answer 21

Protonation lol
