Question

Write in tabular form the relevant physical constants for heptane and the monochlorination products you have listed above 2. 3. Answer the following questions about the procedures given below. What has been done in this experiment to minimize the reaction of the monochlorination products with additional chlorine radicals to give di- and trichloro products? (Consider possible ways to prevent multiple chlorinations.) a. What is the purpose of the sodium bicarbonate washes in the purification of the monochlorinated heptanes. b. The gas chromatogram of your product mixture should show separation of the primary from the secondary products. Referring to your physical property data, predict which compounds you would expect to elute from the column first - the primary product or the mixture of secondary products? Explain. c. Experimental Procedure ty Considerations

Explanation / Answer

Answer:

a) By adding the HCL and the bleach to the dropper bottle to begin generating chlorine. After adding, remove the dropper cap to force the chlorine gas into the tubing. Then you will see the bubbles of Cl2 flowing out of the end of the tube which is immersed in the heptane. Swirl it. When the bubble gets slow, add the remaining HCL and cap quickly to generate more chlorine gas.

b) The mixture is cooled and neutralized with sodium bicarbonate solution. Each phase is washed and heptane is removed from the organic phase under vaccum.

C) when we run a gas chromatogram of the sample to analyse the product we formed. Then we will observe that the separation is achieved on the GC between the primary and the secondary products but no separation is observed within the secondary products. So, therefore because the structure and boiling point are so similar, all the secondary products will elute as one peak.
