    Molecule with +ve and -ve charge at different locations on a molecule.

    how is this stable?

    Its stable, the charges cancel out each other, this happens pretty often for amino acids

    why dosent the electron move toward the exposed proton ?

    does it have something to do with electron shells filling up?

    so the RHS is favoured because it is a lower energy state right?

    It depends on the Ka and Kb value for proton transfer, it doesn't mean it will always work

    Normally, amino acids in solution of water are required to induce zwitterion formation in a given amino acid molecule. First reaction: \[H_2NCH_2CO_2H + H_2O \leftarrow \rightarrow H_2NCH_2COO^- + H_3O^+\] Second reaction: \[H_2NCH_2CO_2H + H_2O \leftarrow \rightarrow ^+H_3NCH_2COOH +OH^-\] Overall reaction: \[H_2NCH_2CO_2H \leftarrow \rightarrow ^+H_3NCH_2COO^- \] You can also say that water plays an important role in inducing zwitterion formation. But the yield depends on equilibrium constant K, and amount of water, large K value means the forward direction is favored.
