$n-$octane

Vedclass · Answer

(C) The boiling point of alkanes is directly proportional to their molecular weight and surface area. $n-$octane $(C_8H_{18})$ has the highest molecular weight among the given options ($n-$hexane: $C_6H_{14}$,isooctane: $C_8H_{18}$ (branched),$2,3-$dimethylbutane: $C_6H_{14}$). Since $n-$octane is a straight-chain alkane with the highest molecular weight and greater surface area compared to its branched isomers,it exhibits the highest boiling point.

Which of the following compounds has the highest boiling point?
