3.1 Provide products formed from the reaction of cyclohex-2-en-1-one with reagents shown below (A - E) cyclohex-2-en-1-one E CH3MgBr C NaBH4 A (CH3CH2)2CuLi LiAlH4 B

Illustrate the structure of the compounds using the following:A. major product between 1,4-dimethylcyclohex-1-ene and BH3, H202, OH-B. major product Of 4-methylpent-2-ene reacted with mCPBA, H20, H+C. major product between 1-methylcyclobut-1-ene and Br2 in dark conditionsD. alkene that formed propanone and carbon dioxide upon reaction with O3, Zn, H2O, H+

A chemist allows some pure (2S,3R)-3-bromo-2,3-diphenylpentane to react with a solution of sodium ethoxide(NaOCH2CH3) in ethanol. The products are two alkenes: A (cis-trans mixture) and B, a single pure isomer. Under thesame conditions, the reaction of (2S,3S)-3-bromo-2,3-diphenylpentane gives two alkenes, A (cis-trans mixture) and C.Upon catalytic hydrogenation, all three of these alkenes (A, B, and C) give 2,3-diphenylpentane. Determine the structuresof A, B, and C; give equations for their formation; and explain the stereospecificity of these reactions

Which stereoisomer of 3-hexene forms (3S,4S)-4-bromo-3-hexanol and (3R,4R)-4-bromo-3-hexanol when it reacts with Br2 and H2O?
