Final answer:
The further oxidation of CH3CH2CH2CHO (butyraldehyde) produces butanoic acid (CH3(CH2)2COOH). This is a two-step oxidation process where a primary alcohol is first converted into an aldehyde and then into a carboxylic acid.
Step-by-step explanation:
The oxidation of CH3CH2CH2CH2OH, which is a primary alcohol (butanol), first produces an aldehyde CH3CH2CH2CHO (butyraldehyde). Upon further oxidation, this aldehyde is converted into a carboxylic acid. Specifically, butyraldehyde can be oxidized to butanoic acid (CH3(CH2)2COOH).
In general, the oxidation of primary alcohols proceeds through the formation of an aldehyde, which can then be further oxidized to a carboxylic acid. This process can be catalyzed by oxidizing agents such as potassium dichromate (K2Cr2O7) in an acidic solution.
