Vedclass · Accepted Answer

$n-C_4H_9OH > n-C_4H_9NH_2 > (C_2H_5)_2NH > C_2H_5N(CH_3)_2 > C_2H_5CH(CH_3)_2$

Vedclass · Answer

(A) The boiling point depends on intermolecular forces such as hydrogen bonding,dipole-dipole interactions,and London dispersion forces.$1$. $n-C_4H_9OH$ (primary alcohol) has strong intermolecular hydrogen bonding.$2$. $n-C_4H_9NH_2$ (primary amine) has hydrogen bonding,but it is weaker than in alcohols due to the lower electronegativity of $N$ compared to $O$.$3$. $(C_2H_5)_2NH$ (secondary amine) has fewer hydrogen bonds than primary amines due to steric hindrance.$4$. $C_2H_5N(CH_3)_2$ (tertiary amine) lacks hydrogen bonding.$5$. $C_2H_5CH(CH_3)_2$ (alkane) has only weak London dispersion forces.Therefore,the order $n-C_4H_9OH > n-C_4H_9NH_2 > (C_2H_5)_2NH > C_2H_5N(CH_3)_2 > C_2H_5CH(CH_3)_2$ is correct.
