Question:

Why are hydrocarbons insoluble in water?

Expert Verified Solution:

Answer Description: Hydrocarbons are insoluble in water due to their nonpolar nature. Water is a polar solvent, meaning it has a slight positive charge on one end and a slight negative charge on the other. This polarity allows water molecules to interact strongly with other polar molecules or ionic compounds. However, hydrocarbons are composed only of carbon and hydrogen atoms, which share electrons relatively equally, making hydrocarbons nonpolar. Since “like dissolves like,” nonpolar substances like hydrocarbons do not mix well with polar substances like water, leading to their insolubility.

This concept is fundamental in understanding the behavior of different molecules in chemical solutions, making it an important topic in chemistry. By understanding why hydrocarbons and water do not mix, one gains insight into broader principles of solubility, molecular interactions, and chemical bonding.
