Consider the structure of noradrenaline. A question asked to draw the structures of the products when noradrenaline reacts with HCl and NaOH separately.
Now I know from the study of hydroxyl compounds that the proton in an -OH group is replaceable. In the case of NaOH, the H from the OH is replaced by a Na+ ion. My answer consisted of a structure where ALL THREE -OH became -ONa but as per the mark scheme only the -OH attached to the ring became -ONa. Please tell me why not the hydroxyl group in the hydrocarbon chain as well?
I also remember that alcohols are amphoteric and accept a proton too. My answer was a structure where all three -OH became -OH2+ and ofcourse the -NH2 became -NH3+. again the mark scheme showed a structure with only the amine group having gained a proton. Help.
Maybe I should post this in biochemistry section aswell?
