WitrynaThe NaOH solution contained 5.00 mL=1.00 mmol NaOH Comparing the amounts shows that CH3CO2H is in excess. Because OH − reacts with CH3CO2H in a 1:1 stoichiometry, the amount of excess CH3CO2H is as follows: 5.00 mmol CH3CO2H − 1.00 mmol OH − = 4.00 mmol CH3CO2H Witryna24 maj 2024 · In order of decreasing importance, the factors impacting S N 2 reaction pathways are 1) structure of the alkyl halide 2) strength of the nucleophile 3) stability of the leaving group 4) type of solvent.
