Are akyl halides(I, Br, Cl) better leaving groups than
tosylate, mesylate, and triflate?
this khan academy table ranks them and it seems like
HI is the best leaving group
my teacher says these sulfonate esters are "super
leaving groups".
Why are they "super" if they aren't even close to HI
if HI is the best leaving group?
if my observation is incorrect and they are better
leaving groups than akyl halides, please explain how.
thanks
