💡 Solution & Explanation

Correct option: \(\text{C}\). Hydrocarbon reactions are decided by bond type: alkanes mainly substitute, alkenes/alkynes add across multiple bonds, and aromatic rings undergo electrophilic substitution. Recovered question text: 18. The order of reactivity of halogens towards halogenation of alkanes is (A) F > Br > Cl > I (B) F > Cl > Br > I 2 2 2 2 2 2 2 2 (C) Cl > F > Br > I (D) Cl > Br > F > I 2 2 2 2 2 2 2 2
