2. The reaction of 2-bromo-2-methylbutane with sodium ethoxide at 50 °C leads to the formation of 2-methyl-2-butene.
1. The major product of the reaction of cis-2-methylcyclohexyl chloride with sodium azide in methanol is A. trans-2-methylcyclohexyl chloride; B. cis-2-methylcyclohexyl azide; C. trans-2- methylcyclohexyl azide; D. 1-methylcyclohexene; E. 3-methylcyclohexene.
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
