Nucleophiles that are Neutral?

Postby Michael_Johanis_2K » Mon Feb 27, 2017 1:02 pm

Page 144 of "Introduction to Organic Chemistry" states that nucleophiles are "often negatively charged, although they can also be neutral." The text then states that H2O, NH3, and NH2CH3 are examples of nucleophiles.

What makes H2O, NH3, and NH2CH3, by definition "electron-rich"? What tell us that a species is electron-rich or electron-deficient?

If you remember from chem 14a, some atoms may have empty orbitals. Filling these will give the atom increased stability and therefore they attract electrons to fill up these orbitals.

H20 also has lone pairs, which could be attracted to the positive electrophiles.
