Question 14

When we add electronegative atoms…

Answer 14

The acidity of our acidic functionality increases

Question 15

Inductive Effect

Answer 15

Change in electron density due to electron-withdrawing and electron-donating groups
- results in a permanent dipole in a bond (has both negative and positive ends)
- rely on electronegativity
- takes place through covalent bonds

Question 16

Electron-Withdrawing Group

Answer 16

Group/Atom that draws electrons toward itself

Question 17

Electron-Donating Group

Answer 17

Group/Atom that gives electrons to other atoms through resonance/inductive effects

Question 18

Anilines

And compare it to amine

Question 19

Pyridine

And compare to imine

Question 20

Describe Pyrrole

Compare to pyridine

Question 21

Active Methylene

And describe

Answer 21

Carbon in the alpha position relative to two carbonyl groups
- protons are more acidic because charge can be localized to two different oxygens

Answer 22

Rearrangement

Question 23

Keto-Enol Tautomerism

Answer 23

Equilibrium between a keto and enol form

Question 24

Imine-Enamine Tautomerism

Answer 24

Equilibrium between an imine and enamine form

Question 25

Zwitterion

Answer 25

Has both a negative and positive formal charge
