Show hintHide hint
Think of what types of species can act as electron donors.
Question 2.
What does SN1 stand for?
Show hintHide hint
Focus on the number of steps in this mechanism.
3Question 3.
What is the main difference between the SN1 and SN2 mechanisms?
- SN1 is bimolecular and one step, SN2 is unimolecular and two steps.
- SN2 is bimolecular and one step, SN1 is unimolecular and two steps.
- SN1 involves inversion, SN2 does not.
Show hintHide hint
Consider the molecularity and steps of each mechanism.
4Question 4.
True or False: Tertiary haloalkanes favor the SN2 pathway.
- True
- False
Show hintHide hint
Think about how the structure of the haloalkane affects nucleophilic attack.
Question 5.
