(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
Any organic compound must have no plane of symmetry in order to be chiral or optically active. The compounds with any plane of symmetry are achiral and optically inactive.
