Hi, could you please give an explanation to? thanks!
What solvent would be best to carry out the substitution of the benzyl iodide shown below and why? H2N solvent at 70 °C 1.0 equivalents Methanol, because this reaction performs best with a polar protic solvent to solvate charged intermediates. DMSO, because this reaction performs best with a polar aprotic solvent which will dissolve the nucleophile without hydrogen bonding. O Hexanes, because this reaction performs best with a nonpolar solvent to...
