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...

13. Which of the following cations is the A. A B.B C.c D.D E.E 14. Given the following substitution reaction, what would the effect be of changing the solvent from CH3OH to (CH3)2SO? CH3(CH2)sBr + NaOH - CH3(CH2),OH + Br A. The rate would increase because Sy2 reactions favor a polar aprotic solvent. B. The rate would decrease because Syl reactions favor a polar protic solvent. C. The potential change cannot be predicted. 15. Which compound is most likely to...
