Strong oxidising agents such as acidified potassium permanganate are used for getting carboxylic acids from alcohols directly. $\ce{CrO_3}$ in anhydrous medium is used as the oxidising agent for the isolation of aldehydes.$\text{RCH}_2\text{OH}\xrightarrow{\text{CrO}_3}\text{RCHO}$
A better reagent for oxidation of primary alcohols to aldehydes in good yield is pyridinium chlorochromate $\ce{(PCC)},$ a complex of chromium trioxide with pyridine and $\ce{HCl}.$
