What major product forms from the following E2
elimination reaction?
Answer options:
Question 4 1.5 pts What major product forms from the following E2 elimination reaction? CH3 Br excess KOH ethanol, heat CH3 Hints: (1) Please be sure you understand where the possible anti-periplanar eliminations can occur for this substituted cyclohexane. Therefore, it is recommended that you convert the starting alkyl halide into its chair structural representation. (2) The ring beta-proton should be trans to the alpha-halogen leaving group in...

Tulung ate n illud aludke place in a single step. In the Sn2 reaction, the nucleophile attacks the a-carbon from the backside and displaces the leaving group with an inversion of configuration occurring at the carbon. In the E2 elimination reaction, strong base removes an acidic hydrogen from the B-carbon and an alkene is formed as the leaving group is expelled from the a-carbon. This elimination follows Zaitsey's rule whereby the more substituted alkene is generally formed. In E2 elimination,...
