Hexanal

Vedclass · Answer

(D) The boiling point of aldehydes and ketones increases with an increase in the molecular mass due to the increase in the magnitude of intermolecular van der Waals forces of attraction. Among the given options,$Hexanal$ $(C_6H_{12}O)$ has the highest molecular mass compared to $Ethanal$ $(C_2H_4O)$,$Propanal$ $(C_3H_6O)$,and $Pentanal$ $(C_5H_{10}O)$. Therefore,$Hexanal$ has the highest boiling point.

Which among the following has the highest boiling point?
