Question
1. In the radical chlorination of butane, a large excess of 1-chlorbutane is used. How would the results change if there was a 1:1 molar ratio of sulfuryl chloride and 1-chlorobutane. (in the original lab there 0.16mL sulfuryl chloride and 0.50mL of 1-chlorobutane)
2. If you were allowed to run the gas chromatogram for the radical chlorination of butane for a longer time, there would be several smaller peaks at larger retention times besides the five peaks that represent the isomers. What would those compounds be and how would it look if there was a 1:1 molar ratio as mentioned in question 1?
Explanation / Answer
Free radical chlorination of butane with 1-Chloro butane will restrict only mono chlorinated products. But adding sulfuryl chloride will give dichloro products also. So we will get a mixture of mono chloro as well as dichloro butanes.
Secondly when we are doing the gas chromotogram for longer time we will get the peaks for isomerisation products. They will be observed as smaller peaks
