Ethanol vs. Isopropanol: What's the Difference?

Edited by Huma Saeed || By Sumera Saeed || Published on December 25, 2023
Ethanol is a two-carbon alcohol (C2H5OH), commonly found in beverages; isopropanol is a three-carbon alcohol (C3H8O), used as a disinfectant.

Key Differences

Ethanol, also known as ethyl alcohol, is a primary alcohol with two carbon atoms and a characteristic intoxicating effect, widely used in alcoholic beverages. Isopropanol, or isopropyl alcohol, is a secondary alcohol with three carbon atoms, primarily used as an antiseptic and solvent.
