$n-$Hexane

Vedclass · Answer

(A) The boiling point of alkanes depends on the surface area of the molecule. As the branching in the alkane increases,the surface area decreases,which leads to weaker van der Waals forces of attraction. Therefore,the boiling point decreases as the number of branches increases. Comparing the given isomers of $C_6H_{14}$: $1$. $n-$Hexane (straight chain) has the largest surface area. $2$. $2-$Methylpentane and $3-$Methylpentane have one branch. $3$. $2,2-$Dimethylbutane has two branches (most compact). Thus,$n-$Hexane has the highest boiling point.
