in case of aldehydes and ketones 2,4 DNPH reacts similar to the nucleophilic addition of HCN and gives a hydrogen to Oxygen in carbonyl group and than the whole rest of the molecule is joined to the carbon like addition of CN and than the OH and H on nitrogen which bonds with carbon of aldehyde or ketone form water so condensation occours and finally C forms double bond with N this organic compound is formed as ORANGE precipitate :)

thnx but im not geting my answer in the f part of question nmbr 5 here :( http://www.xtremepapers.com/papers/...d AS Level/Chemistry (9701)/9701_w05_qp_2.pdf

just make the exact same compound shown except remove the H2 from the nitrogen on top and join it with the aldehyde formed watever it is ..... to join the aldehyde use the carbon to which the carbonyl group was attached to remove the carbonyl group and double bond that carbon with nitrogen of 2,4 DNPH
oh thnx i 4got 2 luk @ cyclohexane -_- but thnx 4 reminding:D
