CHEM 333 Exam 3 Reactions

what are these categorized as, and what reaction(s) do they lead to?

weak/weak

SN1 and E1

what are these categorized as, and what reaction(s) do they lead to?

strong/weak

SN2

what are these categorized as, and what reaction(s) do they lead to?

weak/strong

E2

what are these categorized as, and what reaction(s) do they lead to?

strong/strong

SN2 (if methyl or 1°) or E2 (if 2° or 3°)

what degree of must the R group be for an SN1 reaction to proceed and why?

3° > 2° due to hyperconjugation

what is the mechanism for an SN1 reaction?

what degree of substitution must the R group be for an SN2 reaction to proceed and why?

methyl > 1° > 2° because SN2 reactions are sensitive to crowding

what is the mechanism for an SN2 reaction?

what degree of substitution must the R group be for an E1 reaction to proceed and why?

3° > 2° due to carbocation stability trends

what is the mechanism for an E1 reaction?

what degree of substitution must the R group be for an E2 reaction to proceed and why?

1°, 2°, or 3° (can’t be methyl because then there is no room to make the carbon-carbon double bond)

base and H also must be anti-periplanar!
