(a)
Interpretation:The major product of indicated reaction should be identified.
Concept introduction: The carbonyl bond is polar with partial postive charge on carbon and partial negative charge on oxygen as illustrated below.
Thus it can undergo hydride addition at carbon and proton addition at oxygen. Certain reagents that are useful for such hydride addition at carbonyl carbon include sodium borohydride, lithium aluminum hydride. The boron and lithium in these reagents tend to push the electron of

The reaction proceeds through a cyclic intermediate known as a bromonium ion. The reaction occurs in an anhydrous solvent such as CH,Cl,. In the second step of the reaction, bromide is the nucleophile and attacks at one of the carbons of the bromonium ion to yield the product. Due to steric clashes, the bromide ion always attacks the carbon from the opposite face of the bromonium ion so that a product with anti stereochemistry is formed. Draw curved arrows to show the movement of electrons in this step of the mechanism. Arrow-pushing Instructions CH3 CH3 CH3 CH3 H3C H3C :Br: :Br:arrow_forward
