# Does the carbocation rearrangement in a SN1 reaction specify a change in degree?

I am asked to determine whether the following process is likely to involve a carbocation rearrangement or not:

I think it is possible through the rearrangement given above (though the rearrangement cannot become a secondary or primary carbocation). Can someone please clarify if the carbocation rearrangement specifies a change in degree?

• I feel your wording is a bit unclear. Do you mean to ask that whether this rearrangement is possible and whether it will be called a carbocation rearrangement even though there is no change in the degree of the carbocation? May 15 '15 at 4:46
• How do you say the rearrangement cannot become a secondary or primary carbocation? And as Binary Geek there is no change inthe degree of the carbocation provide sime clarity. By what reference your thinking it is possible ? May 15 '15 at 5:25
• What I get of your question, the process you have made is not possible. It will help if you c;arify. May 15 '15 at 7:36
• Try to draw the mechanism for the second transformation and you'll have your answer. May 15 '15 at 15:08
• @jerepierre That's why I added ~ ? to the arrow when I replaced the drawing ;-) May 19 '15 at 7:38
