Answer to Question #209951 in Organic Chemistry for mlindi

Question

Consider the compounds, propan-1-ol (CH3CH2CH2OH) and propan-1-amine  (CH3CH2CH2NH2). Which of the following statements is INCORRECT?    (1) Propan-1-ol has a higher boiling point than propan-1-amine (2) The O-H bond is more polar than the N-H because oxygen is more electronegative than nitrogen. (3) Alcohols form stronger hydrogen bonds than amines and have higher boiling points.  (4) Propan-1-amine has a higher boiling point than propan-1

Answer 1

Primary and secondary amines have higher boiling points than those of alkanes or ethers of similar molar mass because they can engage in intermolecular hydrogen bonding. ... Because all three classes of amines can engage in hydrogen bonding with water, amines of low molar mass are quite soluble in water.
