When a mixture containing one mole each of the three dimethylbenzenes (o-, m-, and p-xylene) is treated with one mole of chlorine in the presence of a Lewis acid catalyst, one of the three hydrocarbons is monochlorinated in 100% yield, whereas the other two remain completely untouched.
a. Which isomer reacts? (m-zylene, o-zylene, or p-zylene?)
b. Draw the product expected.
c. The same experiment carried out on a mixture of the following three trimethylbenzenes gives a similar outcome. Draw the product of the one benzene that reacts.

Problem 4.40 Sequential Distillation A liquid mixture containing 30.0 mole% benzene (B), 25.0% toluene (T), and the balance xylene (X) is fed to a distillation column. The bottoms product contains 98.0 mole% X and no B, and 85.5% of the X in the feed is recovered in this stream. The overhead product is fed to a second column. The overhead product from the second column contains 91.0% of the B in the feed to this column. The composition of this...

Exercise 2 Separation of a Mixture Based on Acid-Base Properties One purpose of this exercise is to learn how to use a separatory funnel to extract a single component away from other compounds in solution. To do so, we will apply the principles of solubility and acid-base behavior you’re seeing in class. One of the compounds is neutral in the acid-base sense. It has no ability to either donate or accept a proton from an aqueous solution, and will remain...
