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?© BrainMass Inc. brainmass.com October 9, 2019, 6:08 pm ad1c9bdddf
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 ...
The solution provides detailed response to two questions regarding acid elimination reactions, and benzylic carbonation.
