|
Does Delta G have anything to do with exo/endo? |
Nope! |
|
|
What does concerted mean? |
This means it happens in 1 step |
|
|
What does stepwise mean? |
This means it happens in more than 1 step |
|
|
Which reactions don't involve carbocations? |
SN2 & E2 |
|
|
What is the basic principle used to decide the major product of a reaction? |
The more stable product is the major product unless there is some overriding feature in the Transition State. |
|
|
In an aprotic solvent, is Cl or Br a better nucleophile? |
Cl |
|
|
The stereochemistry of every SN2 reaction alwaysi involves... |
Inversion at the carbon bearing the LG because the nucleophile interacts with the carbon leaving group anti bonding orbital. |
|
|
Transition State Definition |
The highest energy structure along the reaction coordinate between reactants & products for every step of a reaction mechanism. |
|
|
In a protic solvent, a smaller atomic radius makes for what kind of nucleophile? |
Poor nucleophile |
|
|
In an aprotic solvent, a smaller atomic radius makes for what kind of nucleophile? |
Good nucleophile |
|
|
What is the best explanation for backside attack and stereochemical inversion for SN2 |
The nucleophile attacks the carbon LG omega* orbital |
|
|
What is the SN2 kinetics rate? |
K[Nuc][Elec] |
|
|
If you double the nucleophile, what happens to the rate? |
The rate doubles |
