Question

Show the rearrangements of the carbon skeleton in the following carbocations. Note that in some cases no rearrangement occurs. As usual, F is the symbol for an aromatic ring. Cp is the symbol for a cyclopentane ring. (a) (CH₃)₃C⁺, (b) CH₃CH₂CH₂CH₂⁺, (c) CH₃CH₂CH⁺CH₃, (d) FCH₂⁺, (e) CH₃CpCH₂⁺ (f) CH₃CH₂CH₂⁺, (g) CH₃CH⁺CH₂CH(CH₃)₂, (h) CH₃CH⁺CH₂CH₂F.

Answer 1

If stability of cation increases than the rearrangement is possible.
