Convert 2-pentanol into 2,3-dibromopentane. Draw structures of the starting material (2-pentanol) and final product (2,3-dibromopentane), and show the two reactions needed for this synthesis. Include the structure of the intermediate compound, and the reagents and conditions for each reaction. Then explain why 1,2-dibromopentane would not be a significant product of this synthesis.

CH3 གོན་ནི། ཡོན་ Br₂, H₂C CH₂Br H3C CH3 H₂C CH3 Aldehydes and ketones can be halogenated at their a-position by reaction with Cl₂, Br2, or 12, under acidic conditions. Using Br₂ under acidic conditions, an intermediate enol is formed which adds bromine at the a-position. The reaction stops after the addition of one bromine because the electron-withdrawing halogen decreases the basicity of the carbonyl oxygen, making the protonation less favorable. Draw curved arrows to show the movement of electrons in this step of the mechanism. Arrow-pushing Instructions :0: :OH н-он H-OH₂ H₂O H₂C. H3C. CH3 CH3 H3C CH3 H3C CH3 Σα
