Please help me to calculate the mass, volume of cyclohexanone EXPERIMENT 4: OXIDATION OF CYCLOHEXANOL TO CYCLOHEXANONEblack, showing presence of unreacted bleach. Because the exact concentration of hypochloritelower layer) with a glass stirring rod and touching it to the test paper. The paper should turnin the bleach solution depends upon its age, it is necessary to make sure that you have an excessof hypochlorite to generate the hypochlorous acid, thus ensuring that the cyclohexanol has beenand carry the reaction out 5 minutes longer. Test again with starch iodide paper to check thatfully oxidized. If the test shows that excess bleach is not present you must add 10 mL of bleachexcess bleach is indeed present. If necessary, add more bleach and run the reaction longer.Repeat this step as necessary until the starch iodide test is positive (test paper turns black).5. After the reaction is completed, the excess hypochlorous acid must be decomposed with a fewmL of a saturated sodium bisulfite solution. Add enough sodium bisulfite until the starchiodide test is negative (test paper does not turn black). A few mL may be needed.6. To neutralize the acetic acid to avoid co-distillation with the cyclohexanone, place a few dropsof thymol blue indicator in the reaction flask and add enough 6 M NaOH solution (about 15-20mL) until the solution is neutral as indicated by its blue color.7. Modify your apparatus to do a simple steam distillation by attaching a distillation head,thermometer adapter, thermometer and West condenser to the center opening of the reactionflask. Add a couple of boiling chips. Stopper the two side openings with ground glassstoppers. Replace the magnetic stirrer with a heating mantle connected to a Variac. Attachrubber hoses to the condenser. (No floods please!) Have your instructor check your setupbefore you begin the distillation! Distill over about 50 mL of the solution.Thermometer Adaptor-Distillation HeadSide Openings Stopperedwith Glass StoppersHeating MantleIron RingBlue ClipH₂O INfrom TapH₂O43OUT to drainHeating Mantle plugged into VariacWest Condenserclamped toanother ring standfor support 42EXPERIMENT 4: OXIDATION OF CYCLOHEXANOL TO CYCLOHEXANONEProcedure:Remember to prepare your notebook before arriving at the lab, including the Table ofReagents and Expected Products.1. Set up your apparatus as shown in the figure below, as close to the hood as possible. Gentlyslide a Teflon-coated magnetic stir bar into the 3-neck 250-mL RB flask. The thermometer isheld in place by a thermometer adaptor. All ground glass joints should be lightly greased asusual. The reflux condenser does not need to be connected to tap water.Reflux CondenserSeparatory Funnel-3-neck 250-mL RB Flask-Magnetic StirrerThermometer-Thermometer AdaptorMagnetic Stir Bar2. Place 0.0700 mol (How many mL would this be?) of cyclohexanol into the RB flask. To it add6.00 mL of glacial acetic acid. ДонCAUTION: Handle glacial acetic acid with care! This is pure acetic acid. It isstrongly corrosive and causes serious burns. It is very harmful if swallowed. It is alachrymator (a substance that causes your eyes to water). Do not confuse glacial aceticacid with vinegar, which is only 5 % acetic acid.3. Turn on the stirrer slowly (not the heater!). Make sure the stir bar will not hit the tip of thethermometer. Add 82 mL of a 8.25 % w/w bleach solution (NaOCI (aq)) into the separatoryfunnel and slowly drip the bleach into the solution at such a rate that the temperature staysbetween 40-50 °C. The reaction is exothermic and you do not need to heat this reaction withthe hot plate. However, do not allow the temperature to go below 40°C as the oxidation wouldbe incomplete.4. After all of the bleach has been added and the temperature starts to cool, stir for 15 minutes.then test the solution with starch iodide paper for excess bleach: This is done by firstmoistening the starch iodide paper with water, then bringing a drop of the solution (from the
