The rate of racemization of 2-iodooctane by sodium iodide in acetone is to be compared with the rate of incorporation of radioactive iodine into 2-iodooctane by satisfying the given conditions for each act of exchange. Concept introduction: The conversion of optically pure molecule into the mixture of enantiomers (i.e. racemic mixture) is called racemization. The change in absolute configuration at the chirality center in the substitution reaction is called inversion of configuration. If the absolute configuration at the chirality center remains same in the substitution reaction, it is called retention of configuration.

Hi!! Please provide a solution that is handwritten. Ensure all figures, reaction mechanisms (with arrows and lone pairs please!!), and structures are clearly drawn to illustrate the synthesis of the product as per the standards of a third year organic chemistry course. ****the solution must include all steps, mechanisms, and intermediate structures as required. Please hand-draw the mechanisms and structures to support your explanation. Don’t give me AI-generated diagrams or text-based explanations, no wordy explanations on how to draw the structures I need help with the exact mechanism hand drawn by you!!! I am reposting this—ensure all parts of the question are straightforward and clear or please let another expert handle it thanks!!
