Question

Which carbocation is most likely to rearrange to a more stable form if formed from CH₃CH₂CH₂CH₂CH₂Cl via heterolytic cleavage?

Choose one · Correct answer highlighted

CH₃CH₂CH₂CH₂⁺ CH₃CH₂⁺ CH₃CH₂CH₂CH⁺CH₃ Correct CH₃C⁺(CH₃)CH₂CH₃

Cleavage at CH₂Cl forms CH₃CH₂CH₂CH₂CH₂⁺ (primary). A hydride shift to CH₃CH₂CH₂CH⁺CH₃ (secondary) increases stability via hyperconjugation.
