Elimination occurs when (Z)-3-bromohex-3-ene is treated with NaNH2. Under the same conditions, 1-bromocyclohexeneundergoes elimination much more sluggishly. Explain why
Why does the final product has the opposite configuration compared to the reactant? Shouldn’t it form OMs first, then OMs gets substituted by Cl- via Sn2 (the 1st inversion of configuration) then the Cl- gets substituted by OCH3- (the 2nd inversion of configuration? To my understanding 2 inversions = same configuration
