In lab you will be performing experiments using Sodium (or Potassium) Iodide in Acetone to determine reactivity in SN1 reactions and Silver Nitrate in Ethanol to investigate SN2 reactions.
How will you know if an alkyl halide is moderately reactive in either test?

In this exercise, you will use two reagent mixtures to test a variety of organic halides. The distinct differences in the factors affecting the SN2 and SN1 mechanisms make it possible to determine which mechanism is favored by a given compound. One reagent and solvent favors SN2 reactivity, the other SN1 reactivity. From the results of your tests, you will determine which mechanism, if either, is favored by a given compound. In your post-lab assignment, you will be required to...

3. An alkyl halide is reacted with sodium iodide and sodium chloride in separate test tubes. The rate was the same in both experiments. Is this an Syl or an SN2 reaction? How would you know? 4. Why is sodium iodide used as a solution in acetone in these experiments instead of a solution in water? 5. Will the reaction below be Spl or Sn2? Show the mechanism.

1. In both the sodium iodide
test and the silver nitrate test, why does 2-bromobutane react
faster than 2-chlorobutane?
Bromine is a better leaving group since it is a weaker base than
chlorine is.
2. a. Why does benzyl chloride react under both
SN1 and SN2 conditions?
Benzyl
chloride is a primary alkyl halide, hence reactive under SN2
conditions.
The
primary carbocation formed due to the departure of Cl- is
stabilized by the pi electrons in the benzene ring.

Nitrate is a
a. very good electrophile
b. very poor electrophile
c. very poor nucleophile
d. very good nucleophille
ethanol is
a. non-polar aprotic or proatic
b. polar
silver ion will coordinate very efficiently with any free
halide and form a precipitate, promotiong the ionization of
halohydrocarbons and formation of
a. resonance
b. carbocations
c. carbanions
Thus, the AgNO3/ethanol reagent favors reactivity by the
a. SN1
b. SN2
