If you go on this link and go to question 2 b,the answer jn the markscheme shows a ketone,but im confused why it MUST be a ketone?? Because the way we studied it is even if it forms a carboxylic acid or an aldehyde the color still goes from orange to green but the markscheme strictly shows an aldehyde,why is that??

Question 2B is asking you about the oxidation of alcohol B. Alcohol B can only oxidise to become a ketone as it is a secondary alcohol. Primary alcohols oxidise to aldehydes and then to carboxylic acids under acid reflux with acidified potassium dichromate.
