Why it is easier for the carbonyl group to lose a proton to become negatively charged and the amino group to accept a proton to become positively charged ?
I know it has to do with the very polar bond due to the oxygen . And the H+$\ce{H+}$ ions attracted to the lone pair of electrons on N$\ce{N}$ in the amino group .
But I don't understand why would aan electronegative atom Oxygen wantsuch as oxygen wants to lose a proton ?.
I was told that they will attract more electrons towards towards them . But that does not help in my understanding of why protons will leave . Thanks !
