E1 reaction with oh

WebAn E1 reaction requires a weak base, because a strong one would butt-in and cause an E2 reaction. In an E1 reaction, the base needs to wait around for the halide to leave of its own accord. In the video, Sal makes … WebWhich of the following statements about an E1 mechanism is not true? A) It is a two-step process and has the same first step as an SN1 mechanism. B) It involves the formation of a carbocation from eliminating a good leaving group. C) A common competing reaction is rearrangement of a less stable carbocation to a more stable carbocation.
