Among the following, select the alkane that is expected to have lowest boiling point?
Text Solution
Verified by ExpertsThe correct answer is:
D
As number of 
atoms increases in alkanes, the Van der waal's forces also increase. However, branching results in decrease in boiling point due to decreased surface area which results in weaker Van der waal forces, Thus; order of boiling point of given alkanes is
Hexane 
-Methyl pentane 
- methyl pentane 
dimethyl butane.
