reactivity Flashcards
SN2 rtxn
sodium or potassium iodide
alkyl halide reactivities are?
nucleophilic substitution reactions
-they depend on rxn conditions and the structure of the substrate
iodide ion
nucleophile
acetone
nonpolar solvent
precipitate
forming it increases the rxn completeness
sodium and potassium iodide
soluble in acetone
bromides and chlorides ions
-precipitate
-not soluble in acetone
-produced in the rxn
lechatlier princliple
if precipitate is formed as product the equilibirum runs right
chloride and bromide equations
R-Cl + Na^+ I^- –> RI + NaCl
R-Br + Na^+ I- –> RI + NaBr
silver nitrate in ethanol
SN1
nitrate ion
poor nucleophile
ethanol
ionizing solvent
silver ion
helps in the ionization of alkyl halide because it it leaves the halide ion to form a silver halide precipitate
white precipitate
positive reaction (ignore all other colors)
