III- Explain each of the following observations or products: a- Reduction with LiAlH4 gives a diol but reduction with diborane gives a hydroxy ester. b- Diimide reduces unconjugated alkenes faster than conjugated alkenes.(JACS. 1961, 83, 4302) c- Treatment of benzene with Na/NH3/EtOH gives 1,4cyclohexadiene, whereas similar treatment of cyclohexene with this reagent gives no reaction. d- L-Selectride gives greater diastereoselectivity in this reduction than does sodium borohydride. Predict the major product
