Alkyl HalidesSolvent Effect on SN2 Reaction26Choose the best answerPolar aprotic solvents favor SN₂ reactions because they:AStrongly stabilize carbocations.BStrongly hydrogen-bond to anionic nucleophiles.CSolvate anionic nucleophiles relatively weakly, increasing their reactivity.DConvert nucleophiles into leaving groups.
