In dry acetone reaction follows SN 2 mechanism Hence, <img class="img-fluid question-image" alt="image" src="https://cdn.tardigrade.in/img/question/chemistry/8e0e23208c270e257fc4618e32651b16-.png" />

Q. The reactivity of alkyl bromides

Towards iodide ion in dry acetone decrease in the order

IV > I > II > III

I > IV > II > III

III > II > I > I

III > II > IV > I

In dry acetone reaction follows $S N^{2}$ mechanism Hence,
