Question

Which of the following carbocations are most likely to rearranger CHE CH3 CH3 © CH2 a) III, IV b) I, II c) II, IV nav d) I, I

Answer 1

Answer #1

I is tertiary carbocation which is most stable already.

So, there will not be any rearrangement.

II is secondary carbocation and it can form tertiary carbocation.

So, it will rearrange.

III is secondary carbocation but its neighbour carbon also are secondary.

So, there will not be any rearrangement.

IV is primary carbocation and it can form tertiary carbocation.

So, it will rearrange.

Answer: c) II,IV
