The empirical formula gives the simplest whole number ratio of the atoms of each element in a compound. In this case, the empirical formula is \(\mathrm{C}_{3} \mathrm{H}_{6} \mathrm{O}\). Since alcohols only contain carbon, hydrogen, and oxygen atoms, the molecular formula for these alcohols will be the same as the empirical formula.

Now, we will draw the structural formulas for different alcohols that have the molecular formula \(\mathrm{C}_{3} \mathrm{H}_{6} \mathrm{O}\), considering different positions of the hydroxyl group (-OH) in the molecule. 1. Propanol (Primary alcohol): In this structure, the hydroxyl group is attached to the first carbon atom. Structure: H–C\( \displaystyle\text{H} \)–C\( \displaystyle\text{H} \)–C\( \displaystyle+_2\text{H} _\text{OH}\) 2. Isopropanol (Secondary alcohol): In this structure, the hydroxyl group is attached to the second carbon atom. Structure: H–C\( \displaystyle\text{H} \)–C\( \displaystyle(_\text{OH} _3\text{H}) \)–C\( \displaystyle\text{H} _{_2}\) These are the two possible isomers of alcohols with the empirical formula \(\mathrm{C}_{3} \mathrm{H}_{6} \mathrm{O}\).
