Iodoform equation
WebCan you write equations for any reactions occurring? Why do you think that these reactions serve such a useful purpose in identifying aldehydes and ketones? Aldehydes and ketones will also form derivatives with hydrazine itself. What is the purpose of using 2,4-dinitrophenylhydrazine in this experiment instead of hydrazine?
