The correct order for homolytic bond dissociation energies (ΔH in kcal/mol) for CH₄ (A), C₂H₆ (B) and CH₃Br (C), under identical experimental conditions, is

Answer: (D)

Solution

Typical bond dissociation energies: D(CH₃–H) ≈ 104 kcal/mol, D(C₂H₅–H) ≈ 98 kcal/mol (slightly weaker, since the resulting ethyl radical is
