Question

In the following partial reactions below, it shows the possibility of 1,2-alkyl and 1,2-hydride shifts. Which is expected to occur? Explain your answer.

Diagram showing 1,2-alkyl and 1,2-hydride shifts in carbocation rearrangements.

Accepted Answer

Path (i) is expected to occur because it results in a more stable carbocation.

Answer

Path (ii) is expected to occur because alkyl shifts require less energy.

Answer

Path (i) is expected to occur because hydride shifts require less energy.

Answer

Path (ii) is expected to occur because it results in a more stable carbocation.
