Alkyl Halides

Question
2 out of 9
 

Pick out the compound with the highest boiling point.

A 1-Chloroethane
B 1,1-Dichloroethane
C 1,1,1-Trichloroethane
D Cannot be predicted
Ans. C In general, as the number of carbons increases, the boiling point increases. But in this question, all the given choices are derivatives of the same alkane. In other words, they all have the same number of carbon atoms. The compound 1-chloroethane is monochlorinated, the compound 1,1-dichloroethane is dichlorinated, and the compound 1,1,3-trichloroethane is trichlorinated. As the number of Cl atoms increases, the attractive forces also increase, which means the boiling point increases.
