Answer :
Order of carbocation stability - 3° >2°>1°
As we know that tertiary carbocation is more stable than secondry cabocation.
In this compound 2°carbocation convert into 3° carbonation by 1,2 hydride shift.
Therefore, option (v) is correct.

answer all questions
1. For the following substrates, predict whether a carbocation rearrangement will take place in an SN1/E1 mechanism by first drawing the carbocation intermediate, then deciding if the carbocation will rearrange (can it form a more stable carbocation by hydride or methyl shift?): Carbocation: Sturcture Rearrange? If yes, draw the rearranged product. If no, write No н.с Br Н,с, Cн, 2. For each pair of nucle ophiles, circle which will react faster with CHsl in an Sx2 reaction....

1. Rank the following carbocations in order from most stable (1) to least stable (4). o ó no 8 2. Consider the following carbocation. Would this carbocation undergo a rearrangement? If so, show the mechanism (curved arrows) for the rearrangement (including the rearranged cation that is the product of your curved arrows) and explain why it happens. If not, explain why it would not rearrange.
