- Elimination occurs when (Z)-3-bromohex-3-ene is treated with NaNH2. Under the same conditions, 1-bromocyclohexeneundergoes elimination much more sluggishly. Explain whyA 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.
