6.21 part (c)

Can someone explain why the nitro groups on thymine are amphiprotic? And how would you write proton transfer equilibria equations with these groups?

The nitrogens have a lone pair that can accept protons. They can also lose their proton and gain a formal charge of negative one. You can write the equilibria equations the same way you would for any acid-base reactions
