Aldehydes and ketones
Read our general notes on Risk Assessment
Could you please give me the name of the yellow precipitate formed when an aldehyde or ketone reacts with Brady's reagent? Is the same precipitate formed with every aldehdyue or ketone?

In a previous reply I mentioned that these types of compound are called hydrazones, in particular when Brady's reagent is used, they are 2,4-dinitrophenylhydrazones.
Formal naming of a 2,4-dinitrophenylhydrazone of a particular aldehyde or ketone would be complicated, so they are usually just referred to as, for example, 'ethanal 2,4-dinitrophenylhydrazone' or 'propanone 2,4-dinitrophenylhydrazone' etc, or as the 2,4-dinitrophenylhydrazone derivative of - - - -.
Hope this helps? If not, come back to us via Re:act, not email, please.
