In an Sn2 reaction with "CN as nucleophile, [CH:CH:CI | CH:CH;OH_ CH;CH;0Tos] reacts faster because it has a [better / poor] leaving group than the other ones. These types of leaving groups can stabilize the developing [positive charge / negative charge / radical] in the transition state thus lowering Jenthalpy / entropy / aetivation energy]. CH;CH2CH2B1 reacts faster in [water/ CH:CN]. In a polar [protic / aprotic] solvent, the negatively charged nucleophile will be solvated thus becoming more stable and [more / less]reactive.
