Read the wording for your board, then hide it and explain Carbonyl group detection in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: OCR
A carbonyl group is detected chemically by 2,4-dinitrophenylhydrazine, which confirms a carbonyl is present but does not by itself distinguish aldehyde from ketone.
