I have been doing studies in physical organic chemistry and I know the slope of a Grunwald-Winstein graph shows which mechanism is done for example (1) m ≥ 1, the reactions proceed through SN1 mechanism and (2) m < 1, the reactions proceed through a mechanism between SN1 and SN2. Ive only seen m in the decimal form but can it be negative? The only way I could imagine this would be if there were competing mechanisms or if the solvent was going from polar to non polar but I am unsure. If anyone has anything they have read of interest let me know!

  • $\begingroup$ What is a Gurnwald-Winstein graph ? Is it not Grunwald instead ? How can a mechanism be between SN1 and SN2 ? $\endgroup$
