Saturated Hydrocarbons vs. Unsaturated Hydrocarbons: What's the Difference?

Edited by Huma Saeed || By Sumera Saeed || Updated on October 20, 2023
Saturated hydrocarbons contain only single bonds between carbon atoms, while unsaturated hydrocarbons have one or more double or triple bonds.

Key Differences

Saturated hydrocarbons and unsaturated hydrocarbons differ primarily in their chemical structure and properties. Saturated hydrocarbons have all the hydrogen atoms they can possibly hold, which means there are only single bonds between the carbon atoms. Unsaturated hydrocarbons, conversely, contain one or more double or triple bonds between carbon atoms, implying a deficiency in hydrogen.

In saturated hydrocarbons, each carbon atom forms four single covalent bonds with other atoms. This characteristic makes them relatively stable. Unsaturated hydrocarbons, on the other hand, contain carbon atoms connected by double or triple bonds, making them more reactive. The presence of these multiple bonds allows unsaturated hydrocarbons to participate in various chemical reactions.

Saturated hydrocarbons are typically found in solid fats and are less healthy for consumption. They have a higher melting point due to the strong Van der Waals forces between the molecules. Unsaturated hydrocarbons, in contrast, are typically liquid at room temperature, like vegetable oils, and are considered healthier.

The sources of saturated hydrocarbons are often animal fats and certain plant oils. These hydrocarbons are not as susceptible to oxidation, making them less likely to become rancid. Unsaturated hydrocarbons, being more reactive, are more prone to oxidation and can become rancid if not stored properly.
