1. The problem asks about the product of the dehydration of propanol. 2. Dehydration of an alcohol typically involves the removal of a water molecule ($H_2O$) from the alcohol. 3. The general formula for dehydration of an alcohol is: $$\text{Alcohol} \xrightarrow{\text{acid catalyst, heat}} \text{Alkene} + H_2O$$ 4. Propanol ($C_3H_7OH$) can undergo dehydration to form propene ($C_3H_6$). 5. The reaction mechanism involves the elimination of $H$ and $OH$ from adjacent carbon atoms, resulting in the formation of a double bond. 6. The balanced chemical equation is: $$C_3H_7OH \xrightarrow{\text{H}^+, \Delta} C_3H_6 + H_2O$$ 7. Therefore, the main product of the dehydration of propanol is propene, an alkene. 8. This is a common reaction in organic chemistry to convert alcohols to alkenes by elimination of water.
