Draw a stepwise mechanism for the following transformation, using curved arrows to show the movement of electrons at each step. ... Draw a stepwise mechanism for the conversion of acrylonitrile (CH2 = CHC ≡ N) to polyacrylonitrile, –[CH2CHC ≡ N]n–, using ... WebHydrogen halide reactivity order : HI > HBr > HCl > HF (paralleling acidity order). Reaction usually proceeds via an S N 1 mechanism which proceeds via a carbocation intermediate, that can also undergo rearrangement. Methanol and primary alcohols will proceed via an S N 2 mechanism since these have highly unfavourable carbocations.
