Question

Растворяются ли алканы в воде?

Answer 1

Алканы вообще очень плохо растворяются в воде. Они хорошо растворимы в органических растворителях.

Если Вас так интересует, то Высшие алканы, "немного" лучше растворимы в воде, чем низшие.

Answer 2

Can Alkanes Dissolve in Water?

Alkanes are hydrocarbons with only single bonds between the carbon atoms. They are nonpolar molecules, which means they do not have a significant difference in electronegativity between the carbon and hydrogen atoms. This nonpolar nature affects their ability to dissolve in water.

Alkanes do not dissolve in water due to their nonpolar nature. Water is a polar molecule, and the principle "like dissolves like" applies here. Since water is polar and alkanes are nonpolar, they do not mix or dissolve in each other.

This is supported by the chemical principle that "nonpolar substances are not soluble in polar solvents." The nonpolar nature of alkanes prevents them from forming favorable interactions with the polar water molecules, leading to their inability to dissolve in water.

In summary, due to their nonpolar nature, alkanes do not dissolve in water.
