Can anyone tell me the exact mechanism followed when an ether reacts with HI and one of the attached groups is 2 degree alkyl group???I think different mechanisms are followed if HI is conc or Anhydrous..But there is a lot of confusion if somebody knows exact details please share
As per my knowledge when conc.HI is used SN1 mech is followed .
While when anhydrous HI is used SN2 mechanism is followed.
Reaction of concern HI and anhydrous HI( in excess 0f HI) both follow SN2 mechanism because of the polarity of HI and strong nucleophile I(-)
It also follow SN1 mechanism when there is 3 degree carboncation or Resonance stabilised carbon cation.
In anhydrous HI product will mixture of iodide.
