Step 1: Understand what isopropanol is. It is also known as 2-propanol.
Step 2: Identify the structure of isopropanol. It has a hydroxyl group (-OH) attached to a carbon atom.
Step 3: Determine the type of alcohol based on the carbon structure. In isopropanol, the carbon with the hydroxyl group is connected to two other carbon atoms.
Step 4: Conclude that because the hydroxyl group is on a carbon connected to two other carbons, isopropanol is classified as a secondary alcohol.
