How to Write the Formula for Isopropyl alcohol

In this video we'll write the correct formula for Isopropyl alcohol (C3H8O). Isopropyl alcohol is an older name but we can tell a lot about it's structural and chemical formula from the older name. Prop tells us there will be three Carbon atoms. And the word "alcohol" tells us that we will have and OH attached to one of the Carbons. Because we have "iso" at the beginning we assume the OH group will go on the central Carbon. A more definitive name for isopropyl alcohol is 2-propanol. This name makes it clear the OH group goes on the second Carbon atom. You'll also see it written Propan-2-ol which is the official IUPAC name,. For the formula for isopropyl alcohol we can write C3H8O or to more exact and show the chemical structure, CH3CHOHCH3.
