MCAT Question of the Day
    •

    Q:

    		 Given the molecule below, and the choice between the nitrogen and oxygen atoms, where will protonation more likely occur and why?



    		 

    A

    		 Oxygen because there are no delocalized electrons present, meaning it is a stronger base when protonated

    B

    		 Nitrogen because the delocalized electrons on the nitrogen make it more stable, and thus, a stronger base than the oxygen

    C

    		 Oxygen because the delocalized electrons on the nitrogen make it more stable, and thus, a weaker base than the oxygen

    D

    		 Nitrogen because it is more electronegative than oxygen, and once protonated, will have a lower pka than the protonated oxygen
