Please solve this pls pls

Dear Student


We know as the intermolecular hydrogen bonding increases, the boiling point increase. So, due to this reason butan-1-ol should hace higher boiling point than butanal.
And out of pentane and ethoxyethane, pentane has higher molecular weight. So on these basis the order will be,
$Bu\tan -1-ol>bu\tan al>pen\tan e>ethoxyethane.$
