    a. Comment of the fact that erythro-2,3-dibromo-3-phenylpropanoic acid undergoes elimination by an E1 pathway in water solvent, but by and E2 pathway when acetone is used as the solvent.

    b. A benzylic carbonation is generated under the water solvent would the presence of a para CH3O- group on the benzene ring increase or decrease the stability of the benzylic carbocation?

    The E1 mechanism usually occurs when the solvent is a protic one i.e where the solvent can act as a nonbasic nucleophile. So water is a protic solvent and that is the reason why E1 reaction in water as a ...

    Solution Summary

    The solution provides detailed response to two questions regarding acid elimination reactions, and benzylic carbonation.
