What is the Difference Between 2 Propanol and Isopropanol?

🆚 Go to Comparative Table 🆚

The terms 2-propanol and isopropanol refer to the same chemical compound, with the chemical formula C3H8O. The only difference between the two terms is the terminology and how they were derived. Here are the key points:

  • 2-propanol: This is the IUPAC (International Union of Pure and Applied Chemistry) name for the compound, and it was given because a hydroxyl group is attached to the 2nd carbon of a propane molecule.
  • Isopropanol: This is the common name for the compound, and it is derived from its structure. The molecule has an isopropyl group linked to a hydroxyl group, making it a secondary alcohol.

Both 2-propanol and isopropanol describe the same alcoholic compound with the hydroxyl functional group, and they have the same structure, properties, and uses. Some common names for this compound include isopropanol, isopropyl alcohol, and 2-propanol.
