Question
Read your textbook and cross off the incorrect statements for an Sx2 mechanism so that only the correct statements appear. Leaving group (halogen) leaves via heterolytic bond cleavage Nucleophile attacks at the same time leaving group leaves via heterolytic Carbocation forms-maybe unstable carbocation rearranges to a more stable carbocation .Leaving group (halogen) leaves as nucleophile attacks carbon bonded to leaving group 5 member transition state occurs Transition state collapses with opposite stereochemistry as reactant in product Transition state collapses with same stereochemistry as reactant in product Nucleophile attacks the carbocation from the right side producing one product exclusively Nucleophile attacks the carbocation from the left side producing one product exclusively Nucleophile attacks the carbocation from the both sides producing two products Read your textbook and cross off the incorrect statements for an Sw1 mechanism so that only the correct statements appear. .Leaving group (halogen) leaves via heterolytic bond cleavage .Nucleophile attacks at the same time leaving group leaves via heterolytic bond cleavage Carbocation forms-maybe unstable carbocation rearranges to a more stable carbocation .Leaving group (halogen) leaves as nucleophile attacks carbon bonded to leaving group 5 member transition state occurs Transition state collapses with opposite stereochemistry as reactant in product Transition state collapses with same stereochemistry as reactant in product Nucleophile attacks the carbocation from the right side producing one product exclusively Nucleophile attacks the carbocation from the left side producing one product exclusively . . .Nucleophile attacks the carbocation from the both sides producing two productsExplanation / Answer
For SN2 mechanism, following statements will be Incorrect -
a) Carbocation forms may be unstable carbocation rearranges to a more stable carbocation
b) Nucleophile attacks the carbocation from both the sides producing two products
c) Nucleophile attacks the carbocation from left side producing one product exclusively
d) Nucleophile attacks the carbocation from left side producing one product exclusively
e) Transition state collapses with opposite stereochemistry as reactant in product.
For SN1 mechanism, following statements will be Correct -

c) Nucleophile attacks the carbocation from left side producing one product exclusively
d) Nucleophile attacks the carbocation from left side producing one product exclusively
e) Transition state collapses with opposite stereochemistry as reactant in product.
f) Leaving group (halogen) leaves via heterolytic bond cleavage
