Isopropyl Alcohol. Isopropyl alcohol, which is also known as 2-propanol, has the same molecular formula as propanol. The molecular weight of it is around 60 g mol-1. The molecular formula is C 3 H 8 O. Hence, isopropyl alcohol is an isomer of propanol. The hydroxyl group of this molecule is attached to the second carbon atom in the chain. Therefore, this is a secondary alcohol. Melting point of isopropyl alcohol is -88 o C, and the boiling point is 83 o C. It is miscible with water and stable under normal conditions. This is a colorless, clear, flammable liquid.
