Which of the following is true about R - I:
Correct answer: D. All are true
- A. They are most reactive alkyl halide for a given alkyl group
- B. They show maximum boiling point for a given alkyl group
- C. Cannot be prepared directly by reaction of alkanes with I2
- D. All are true
Explanation
i) Due to low bond energy reactivity is highest. (ii) Greater polarizability of "I" increases boiling point. (iii) They are highly reactive and gives reversible reaction so cannot be prepared directly.

About Alkyl Halides
Alkyl halides are named and related to their carbon-halogen structure, polarity and reactivity. The key reactions are nucleophilic substitution by SN1 and SN2 mechanisms and elimination by E1 and E2 mechanisms, including how substrate structure, nucleophile, base, solvent and temperature influence substitution versus elimination.
