Final answer:
Jones reagent and potassium dichromate in sulfuric acid can be used to convert a primary alcohol into a carboxylic acid by a two-step oxidation process involving an aldehyde intermediate.
Step-by-step explanation:
The two reagents that can be used to convert a primary alcohol into a carboxylic acid are Jones reagent (a mixture of chromium trioxide (CrO3) and sulfuric acid (H₂SO4)) and potassium dichromate (K₂Cr₂O7) in sulfuric acid (H₂SO4).
For example, if we have ethanol (a primary alcohol), it can be oxidized to acetaldehyde (an aldehyde) with the help of an oxidizing agent such as Jones reagent. The acetaldehyde can then be further oxidized to form acetic acid, which is a carboxylic acid.
Overall, the oxidation of a primary alcohol to a carboxylic acid involves two steps: first, the alcohol is oxidized to an aldehyde, and then the aldehyde is further oxidized to a carboxylic acid.
