Assignment:
For an SN2 reaction, the effect of solvent polarity is usually much less, but the ability (or really lack there of) of the solvent to solvate the nucleophile is the important criteria.
Which of the two reactions proceed faster:
a.) CH3CH2I in presence of ethanol
or
b.) CH3CH2I in presence of dimethyl sulfoxide
Provide complete and step by step solution for the question and show calculations and use formulas.
