Vedclass · Answer

(B) The boiling point depends on the strength of intermolecular forces,primarily hydrogen bonding and dipole-dipole interactions.$III$ $(CH_3CH_2CH_2COOH)$ is a carboxylic acid,which forms strong intermolecular hydrogen bonds (dimers),leading to the highest boiling point.$I$ $(CH_3CH_2CH_2CH_2OH)$ is an alcohol,which also forms intermolecular hydrogen bonds,but they are generally weaker than those in carboxylic acids.$II$ $(CH_3CH_2CH_2CHO)$ is an aldehyde,which exhibits only dipole-dipole interactions and lacks hydrogen bonding,resulting in the lowest boiling point.Therefore,the correct order is $III > I > II$.

Identify the correct order of boiling points for the following compounds:
$I. \, CH_3CH_2CH_2CH_2OH$
$II. \, CH_3CH_2CH_2CHO$
$III. \, CH_3CH_2CH_2COOH$
