WebThis organic chemistry video tutorial provides a basic introduction into SN2, SN1, E1 and E2 reaction mechanisms. It provides a chart to determine which rea... WebAn SN2 reaction is not possible because this tertiary alkyl halide has too much steric hindrance to undergo an SN2 mechanism. An E1 mechanism is also possible because an E1 mechanism requires a stable carbocation. And an E2 reaction is also possible. So we have three choices for a tertiary substrate. flagship hotel boothbay maine
