Experiment 7 — Nucleophilic Substitution
www.amherst.eduTo encourage an SN2 reaction mechanism you will use a solution of NaI in acetone. Iodide is a good nucleophile, and if it displaces bromide or chloride, NaBr or NaCl will precipitate (these are much less soluble in acetone than NaI). To encourage an SN1 reaction mechanism you will use a solution of AgNO3 in ethanol. Ethanol is a polar protic ...
