$H_3CCH_2CH_2CH_2Cl$

Vedclass · Answer

(A) The correct answer is $H_3CCH_2CH_2CH_2Cl$ (n-butyl chloride).For isomeric alkyl halides,the boiling point decreases with an increase in branching.Branching of the carbon chain makes the molecule more compact,which reduces the surface area.As the surface area decreases,the magnitude of intermolecular van der Waals forces of attraction also decreases.Therefore,straight-chain isomers have higher boiling points compared to their branched-chain counterparts with the same molecular formula.Among the given options,$H_3CCH_2CH_2CH_2Cl$ is a straight-chain isomer,while the others are branched,making it the one with the highest boiling point.

Which one of the following has the highest boiling point?
