Concept explainers
Interpretation:
A mechanism for the reversible equilibrium isomerization of 2-substituted-2-cyclopentanones to 5-substituted-2-cyclopentanones is to be proposed.
Concept introduction:
The steps involved in the reversible equilibrium isomerization of 2-substituted-2-cyclopentanones to 5-substituted-2-cyclopentanones are i) abstraction of a proton from the γ-carbon to form a resonance stabilized enolate ion ii) Protonation at the α- carbon iii) Abstraction of a proton from other α- carbon to form a different resonance stabilized enolate ion iv) Protonation of the γ- carbon.
To propose
A mechanism for the reversible equilibrium isomerization of 2-substituted-2-cyclopentanones to 5-substituted-2-cyclopentanones.

- Please correct answer and don't use hand ratingarrow_forwardThe SN 1 mechanism starts with the rate-determining step which is the dissociation of the alkyl halide into a carbocation and a halide ion. The next step is the rapid reaction of the carbocation intermediate with the nucleophile; this step completes the nucleophilic substitution stage. The step that follows the nucleophilic substitution is a fast acid-base reaction. The nucleophile now acts as a base to remove the proton from the oxonium ion from the previous step, to give the observed product. Draw a curved arrow mechanism for the reaction, adding steps as necessary. Be sure to include all nonzero formal charges.
