Chemistry unit 2 edexcelWatch
Do we need to know about ketones and aldehydes for this exam?
Get hold of the syllabus, either from the Edexcel web site or from your school.
but id gues that they would prefer you to know what is formed after alcohols are reacted with potassium dicromate (VI) wouldnt they?
thus,to be on the safe side,i would suggest that you try understanding the basic concepts of ketones and aldehydes
