$CH_3COOH$

Vedclass · Answer

(A) The boiling point of organic compounds depends on the strength of intermolecular forces. $CH_3COOH$ (acetic acid) forms stable intermolecular hydrogen-bonded dimers in the liquid phase,which significantly increases its boiling point compared to alcohols,amines,and aldehydes of similar molecular mass. $CH_3-CH_2-OH$ and $CH_3-CH_2-NH_2$ also exhibit hydrogen bonding,but it is less extensive than the dimer formation in carboxylic acids. $CH_3-CH_2-CH=O$ (propanal) only has dipole-dipole interactions and lacks hydrogen bonding,resulting in the lowest boiling point among the given options. Therefore,$CH_3COOH$ has the maximum boiling point.

Which of the following has the maximum boiling point?
