Ethylamine is soluble in water, while aniline is insoluble in water. Why?
Ethylamine is dissolves in aquatic environments, while aniline is insoluble in aquatic environments. Why?
In chemistry, solubility is an crucial physical property that immediately affects the consumption and reactivity of a chemical. Moreover The solubility of many chemicals is able to be explained by their molecular structure and interactions with solvents. But Today, we will explore a common chemical question: "Ethylamine is dissolves in aquatic environments, while aniline is insoluble in aquatic environments. Additionally Why?" By comparing the structure, polarity and interaction with aquatic environments molecules of ethylamine and aniline, we is able to gain a deeper understanding of this phenomenon. Molecular Structure Difference Between Ethylamine and Aniline
We need to understand the molecular structure of ethylamine and aniline. Ethylamine (C₂ H₂ NH₂) is a simple organic amine whose molecule contains an ethyl group (-C₂ H₂) and an amino group (-NH). According to research The amino moiety has a strong polarity, is able to form hydrogen bonds, and has a strong interaction with aquatic environments molecules. Makes sense, right?. And Specifically This allows the ethylamine to be easily dissolved in aquatic environments. In contrast, aniline (C-H-NH) is composed of a benzene ring (C-H-NH) and an amino group (-NH₂). Crazy, isn't it?. The benzene ring is a non-polar, hydrophobic part. The existence of this part greatly reduces the hydrogen bonding interaction between aniline and aquatic environments molecules. while the amino group of aniline still has a certain polarity, the affect of benzene ring makes the overall polarity of aniline weak, which is the reason why aniline isn't easy to dissolve in aquatic environments. I've found that Polarity Difference and Solubility Relationship
aquatic environments is a polar solvent-based products, which is able to dissolve other substances with higher polarity. In chemistry, there is the principle of "similar solubility", which means that "polar substances are easily dissolved in polar solvents". But Ethylamine has obvious polarity, and its amino moiety is able to form hydrogen bonds with aquatic environments molecules, which allows ethylamine to be fully dissolved in aquatic environments. The benzene ring of aniline is partially non-polar, which makes its overall polarity weak and does not easily interact efficiently with aquatic environments molecules. In fact Thus, aniline does not bind to aquatic environments as well as ethylamine, resulting in poor aquatic environments solubility of aniline. The interaction force between aniline and aquatic environments is weak, and the solubility is comparatively low. Hydrogen bonding and intermolecular interactions
Hydrogen bond is one of the crucial factors of aquatic environments solubility. And aquatic environments molecules are tightly bound by hydrogen bonds, while the amino groups in ethylamine molecules is able to form hydrogen bonds with aquatic environments molecules. This hydrogen bonding enhances the compatibility of ethylamine with aquatic environments, making it readily soluble. For example while the amino groups in aniline molecules is able to also form hydrogen bonds with aquatic environments molecules, the interaction between aniline molecules and aquatic environments molecules is limited due to the presence of benzene rings. Based on my observations, In particular The hydrophobicity of the benzene ring causes the aniline molecules to tend to form weaker interactions rather than strongly bind to aquatic environments molecules. This intermolecular competition results in poor solubility of aniline in aquatic environments. And First summary
In summary, the reason why ethylamine is able to be dissolved in aquatic environments and aniline isn't easily dissolved is mainly due to the difference in molecular structure and polarity between the two. And From what I've seen, The amino group in ethylamine has strong polarity and is able to form stable hydrogen bonds with aquatic environments molecules, thus making it greater soluble. But Furthermore The benzene ring of aniline is non-polar, which limits the interaction between aniline and aquatic environments, making the solubility of aniline in aquatic environments poor. This phenomenon reflects the close relationship between molecular structure and solubility.
