Propanol is a common alcohol that has three carbon atoms in its molecular structure. However, there are two different forms of propanol, depending on the position of the hydroxyl (-OH) group on the carbon chain. These forms are called 1-propanol and 2-propanol, and they have different properties and uses. In this article, we will explain how to distinguish between 1-propanol and 2-propanol using some simple chemical tests.

Structure and Classification of Propanols
The main difference between 1-propanol and 2-propanol is the location of the hydroxyl group on the carbon backbone. In 1-propanol, the hydroxyl group is attached to the terminal carbon atom, which is at either end of the chain. In 2-propanol, the hydroxyl group is attached to the middle carbon atom, which is not at the end of the chain. This difference in structure affects the classification of propanols as primary or secondary alcohols.
A primary alcohol is an alcohol that has a hydroxyl group attached to a terminal carbon atom, which has only one other carbon atom bonded to it. A secondary alcohol is an alcohol that has a hydroxyl group attached to a non-terminal carbon atom, which has two other carbon atoms bonded to it. Therefore, 1-propanol is a primary alcohol and 2-propanol is a secondary alcohol.
Different Applications
Propan-1-ol is mainly used to produce chemicals such as propane, propylene, and dimethyl carbonate, while Propan-2-ol is widely used in the production of polyethers, coatings, and other applications.
