CBSE · Class 11 · Chemistry · HydrocarbonsWhich of the following compounds has the highest boiling point?
The boiling point of alkanes depends upon the molecular size and surface area. Straight-chain alkanes have larger surface areas compared to branched-chain isomers, leading to stronger van der Waals forces of attraction. Among the given options, n-pentane has a straight chain and thus the highest boiling point compared to its branched isomers like 2-methylbutane and 2,2-dimethylpropane.
