The correct order of reactivity of halogens with alkanes is:
- A \(F_2 > C l_2 > B r_2 > I_2\)
- B \(F_2 > B r_2 > C l_2 > I_2\)
- C \(I_2 > B r_2 > C l_2 > F_2\)
- D \(C l_2 > F_2 > B r_2 > I_2\)
Answer & Solution
Correct Answer
(A) \(F_2 > C l_2 > B r_2 > I_2\)
Step-by-step Solution
Detailed explanation
The reactivity of halogens towards alkanes is determined by the bond dissociation energy of the halogen molecule and the enthalpy of the reaction. The reaction of an alkane with a halogen is represented as \(R-H + X_2 \rightarrow R-X + H-X\). The reactivity order is governed by…
