Which of the following is the correct order of stability for the given free radicals?
- A.
- B.
- C.
- D.
Show correct answer & step-by-step solution
Correct answer: B —
Solution
- Free radicals are electron-deficient species stabilized by hyperconjugation and inductive effects.
- A tertiary radical has nine alpha-hydrogens available for hyperconjugation.
- A secondary radical has six alpha-hydrogens, and a primary radical has only three.
- Greater hyperconjugation leads to increased stability of the radical center.
- Hence the answer is (B).
