Hello! I wanted to ask a question on 2b(iii). I know how to answer this but just for confirmation, do we write all the colours that are mentioned in the mark scheme when they ask us the colour of the precipitate formed with aldehydes and ketones using 2,4-DNPH or just orange ppt is enough?

Hey! It's ok to put just one colour, but i always put yellow-orange because there were mark schemes that didn't accept yellow. But to get the point you need to write the word precipitate or solid :smile:
