What happens when aldehydes are oxidized with potassium dichromate and potassium permanganate?
Answer & explanation
Correct answer: option 1
The correct answer is option 1. Carboxylic acid is formed.
When aldehydes are oxidized with strong oxidizing agents such as potassium dichromate (K₂Cr₂O₇) or potassium permanganate (KMnO₄), they are converted into carboxylic acids. These oxidizing agents are powerful enough to fully oxidize the aldehyde group (-CHO) to a carboxylic acid group (-COOH).
Oxidation Reaction:
The general reaction for the oxidation of an aldehyde to a carboxylic acid can be represented as follows:
