    2,4-DNP only reacts with aldehydes or ketones. Aspirin has a carboxyl and ester functional group, neither of which react with 2,4-DNP

    2,4 - DNP only reacts with aldehydes and ketones. None of those 2 are aldehydes or ketones as aspirin has an ester group and paracetamol has an amide group

    Thank you ! I get it now - I somehow was thinking the presence of c=o makes them carbonyl compounds and forgot that R groups in carbonyl refer to alkyl group (wait thats right, right? )
