You mean, because iodide is a weaker base than chlorine and bromine it can displace the alkyl chloride or bromides?

Any ideas?

The question comes from Williamson's Macroscale and Microscale Organic Experiments. Please respond if you have any ideas.

The addition of sodium or potassium iodide catalyzes many SN2 reactions of alkyl chlorides or bromides. Explain. I think the reason why it catalyzes many SN2 reactions, has to do with the fact that it is the best leaving group of all the alkyl halides. But why else? Also, is the potassium...

A chemist started to carry out column chromatography on a Friday afternoon, got to the point at which the two compounds being separated were about three-fourths of the way down the column, and then returned on Monday to find that the compounds came off the column as a mixture. Speculate on the...

I was looking for something a little less sophisticated. How could you identify citral? My guess is test its boiling point?

anything? somebody has to know something?

If there is no negative charge and no formal charge on a compound how do you identify a nucleophile?

How can you test for the presence of citral?

vacuum distillation is something I just through in there, I simply wanted to know if they separate under a lower pressure, and I think the consensus is that they will. Thanks for the replies.

Can a cyclohexane-toluene mixture be separated if the external pressure is 350mm HG instead of 760 mmHG ? My guess is yes, lowering the atmospheric pressure will only lower the boiling point, it won't affect whether separation will occur. By the way, is this what we call vacuum distillation...

Is this right? Well, is this right? 1) k = 20/13.3 = 1.5 x/30-x = .50 x = .5(30-x) 1.5x = 15 x = 10g in ether layer 30 – x = 20g in water layer x = .5(20 – x) x = 10 -.5x 1.5x = 10 x = 6.67 20 – x = 13.33 x/13.33 – x =.50 x = .50(13.33 – x) x = 6.67 - .5x x = 4.44...

any ideas? anyone?

Suppose a reaction mixture, when diluted with water, afforded 300mL of an aqueous solution of 30 g of the reaction product malonitrile,CH2(CN)2 which is to be isolated by extraction with ether. The solution of malonitrile in ether at room temperature is 20.0 g per 100 mL, and in water is 13.3 g...
