### Reaction Scheme Explanation **Objective:** Complete the following reaction scheme, focusing on stereochemistry. #### Initial Molecule The starting molecule is a secondary alcohol, represented as follows: - The central carbon is bonded to: - A hydroxyl group (OH) on a wedge, indicating it projects outwards. - A hydrogen atom (H) on a dash, showing it extends inwards. - Two additional carbon groups, one being a methyl group. ### Reaction Steps #### Step 1 - The first transformation involves converting the alcohol into an intermediate product denoted as "A". - This step typically involves the replacement of the hydroxyl group, possibly through activation into a better leaving group or via substitution. #### Step 2 - The intermediate "A" is further transformed into the final product. - The final product is an alkyl iodide, where the iodine (I) replaces the initial hydroxyl group. - The stereochemistry is inverted compared to the starting alcohol, with hydrogen now positioned on the wedge and iodine on the dash, indicating a stereochemical inversion. ### Considerations - **Stereochemistry:** Pay close attention to the stereochemical changes, particularly the inversion at the chiral center. This suggests the reaction may proceed via an SN2 mechanism, often characterized by such inversion. This reaction scheme illustrates the transformation of an alcohol to an alkyl iodide with emphasis on stereochemical configuration changes, a crucial aspect for understanding reaction mechanisms in organic chemistry.
