$n-$pentane

Vedclass · Answer

(D) The boiling point of alkanes increases with an increase in the number of carbon atoms due to increased van der Waals forces. For isomers,the boiling point decreases with an increase in branching due to a decrease in surface area. $n-$pentane $(C_5H_{12})$ has five carbon atoms in a straight chain,whereas $2-$methylbutane is a branched isomer with a lower boiling point. $n-$butane has only four carbon atoms,and $2-$methoxypropane is an ether. Comparing the molar masses and intermolecular forces,$n-$pentane exhibits the highest boiling point among the given options.
