<1-Propanol> is the primary <alcohol> $\mathrm{CH_3CH_2CH_2OH}$. Its hydroxyl group lies at an end of the three-carbon chain.
Its constitutional isomer 2-propanol has the same formula but a secondary hydroxyl-bearing carbon. The distinction changes oxidation products: the primary alcohol can form an aldehyde, whereas oxidation of the secondary isomer forms a ketone.
