1) KI in acetone undergoes SN 2 reaction with each P, Q, R and S. the rates of the reaction varies as A) P>Q>R>S B) S>P>R>Q C) P>R >Q>S D) R >P >S >Q Answer: Option BExplanation: Plan Acetone is an aprotic solvent and can dissolve both the nucleophile and the substrate and thus SN 2 reaction is favoured, also Thus, reactivity order is S >P>R>Q
