Methyl acetate: electrostatic potential

Methyl 2,2-dimethylpropanoate, H NMR spectrum of, 459 Methyl acetate, electrostatic potential map of, 791... 

Examine electrostatic potential maps for methyl acetate (X=OMe), dimethylacetamide (X=NMe2), mdacetonitrile. What is die most electron-rich site in each molecule Does this site correspond to a bonding pair of electrons or a nonbonding pair of electrons Assuming that protonation occurs onto the most electron-rich site, where would you expect each molecule to protonate ... 

Electrostatic potential maps of the conjugate bases from methyl alcohol, acetic acid, and acetone are shown in Figure 2.4. As you might expect, all three substances show a substantial amount of negative charge on oxygen. 

Electrostatic potential maps of the conjugate bases of (a) methyl alcohol, (b) acetic acid, and (c) acetone. The oxygen atoms carry much of the negative charge in all three. 

Use SpartanView to examine electrostatic potential maps of ethyl acetate and H-methyl-2-pyrrolidinone. Identify the most basic atoms in each, and draw resonetite structures of the protonated forms.
