regent and solvent question
« on: December 17, 2010, 01:29:07 AM »
What is the reagent and solvent combination which would result in the fastest reaction with methyl bromide (R = CH3 in all cases)?
A) ROH, HMPA
B) RS−, H2O
C) RO−, H2O
D) RS−, DMSO
E) RSH, H2O

I don't know how to start this one at all....
