Web30 Dec 2024 · Also, it is important to realize that the likelihood of the SN1 pathway being taken largely depends on the stability of the carbocation intermediate that forms. The benzylic carbocation that forms in this case is extremely stable: due to resonance and. due the the presence of the polar protic substance, methanol. Thus, SN1 is highly preferred here. WebWrt this 2010 journal, note that " In the SN1 mechanism, the existence of the typical carbocation was not observed" This is in direct contrast to your statement: "At this point, note that the carbocation thus formed may rearrange." Please can you fix this. Thank you! $\endgroup$ – Gaurang Tandon.

Web18 Mar 2024 · In this case the transition state of the reaction is much polar than ground state if the reaction follows the SN1 Pathway. So in presence of polar medium like acetic acid the transition state will be more stabilised than ground state and hence activation energy of the reaction will decrease. And the rate of the reaction will be faster. WebChemistry questions and answers. CHM 255 PSO WORKSHEET 9 SPRING 2024 Please write out your answers and upload to Gradescope. 1.
