40．Zaitsev＇s Rule的笔记
Zaitsev's Rule: Carbon more likely to lose H+ is the one with fewer hydrogens.
37．Nucleophilicity vs．Basicity的笔记
Nucleophilicity:kinetic concept - how good is it at reacting - how fast is it as reacting - how little extra energy does it need to react - matter with solventgood nucleophilicity = good at reactingin protic solvent: I- > OH- > F-in aprotic solvent: OH- > F- > I-Basicity:thermodynamic concept - how stable are the reactants or the products - how badly something would like to react - does not matter with solventOH- > F- > Cl- > Br- > I-
36．Nucleophilicity （Nucleophile Strength）的笔记
Aprotic Solvent:I- > Br- > Cl- > F- (nucleophilicity)(F-: tight "water shell" surrounded due to its small size) Protic Solvent:F- > Cl- > Br- > I- (nucleophilicity)
