The Better Nucleophile

Satisfactory Essays
The bromide ion is the better nucleophile than the chloride ion because of its larger size and since it is a weaker base. The chloride ion is more electronegative than bromide ion, so it tends to hold electrons in closerE. Since the bromide ion is less electronegative and has more electrons, it is able to share unpaired electrons easier than the chloride ion. In the case of this laboratory experiment, bromide was the better nucleophile in the protic solvent containing hydrogen bonded to oxygen of 1-butanol and 2-methyl-2-butanol as the protic solvent molecules formed strong ion-dipole interactions with the negative-charged nucleophile of the bromide ion, which created a solvent barrier around the nucleophileG.
