Oxidation of Secondary Alcohol to Ketones Lab
« on: April 24, 2015, 02:02:38 PM »
In my organic chemistry lab, we performed the oxidation of 2-octanol to 2-octanone. In the lab we used Ca(OCl)2 as the oxidizing agent, and water. The reaction happened in an acidic solution along with CH3COOH and CH3CN. Those two compound got extracted and were washed with Dichloromethane, NaHCO3 and water. Dichloromethane was then evaporated away from the solution and pure 2-octanone was obtained by fractional-distillation.

Starting mass of 2-octanol = 2.987 g
Ending mass of 2-octanone (after distillation) = 2.785 g


I need help with the following:


a.) Write a balanced equation for the reaction:
2 octanol + Ca(OCl)2  :rarrow: 2 octanone
Find it by using oxidation numbers.

b.) Find the theoretical yield by finding the limiting reagent in the balanced equation.

c.) Find the percent yield.

% yield = actual yield / theoretical yield

You must show an attempt before we can help you; that is a forum policy.  However, I will give you a hint.  Assigning oxidation numbers to carbon is dead-easy (assuming you can add and subtract) and is a useful tool.
