Answer 1

Answer #1

when carbonyl groups undergoes the nucleophilic addition reaction and forms the addition product

when aldehyde i.e butanal undergoes the reaction with 2,4 DNP it produces the 2,4 dintro phenyl hydrazone is the product

and with semi carbazide and produces the semicarbazone as follows

all two reactions are nuclephilic addition reactions
