sulfonates in nucleophilic substitutions
« on: November 18, 2004, 06:10:34 PM »
which halide ion would react the fastest with cyclopentyl p-toluenesulfonate in ethanol/water?  would it be I-  Br- Cl- or F-      I was thinking I- since it reacts fastest in an sn2 reaction     but not really sure ???


                                                thanks

I'm not 100 positive but if it is a nucleophilic attack then I is always the most reactive

Isn't the C-I bond very weak?

ethanol/water screams SN1 to me.
Most Common Suggestions I Make on the Forums.
1. Start by writing a balanced chemical equation.
2. Don't confuse thermodynamic stability with chemical reactivity.
3. Forum Supports LaTex
