As per your syllabus, the rate of HALOGENATION of alkanes (F₂, Cl₂, Br₂, I₂) decreases in which order?
AF₂ > Cl₂ > Br₂ > I₂
BI₂ > Br₂ > Cl₂ > F₂
CBr₂ > Cl₂ > F₂ > I₂
DCl₂ > F₂ > Br₂ > I₂
Answer & Solution
Correct answer: A. F₂ > Cl₂ > Br₂ > I₂
syllabus substitution: F₂ > Cl₂ > Br₂ > I₂ (fluorination is too violent, iodination reversible).
