E2 reaction explained

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. WebFeb 6, 2024 · E2 Reaction. An E2 reaction is a type of elimination reaction, where atoms are removed from a compound to form a new pi bond (in the form of a double or triple bond). There are two elimination ...
