Consider an extreme form of elimination where both the abstractable proton and the departing leaving — Reaction Mechanism Chemistry Question

💡 Solution & Explanation

In standard elimination terminology, numbers dictate the relative positions of the leaving atoms. $\beta$ -elimination removes atoms from adjacent carbons (1,2-elimination). When a base removes a proton and a leaving group departs from the very same original carbon atom (as in chloroform forming dichlorocarbene), the process is known as an $\alpha$ -elimination or a 1,1-elimination. Therefore, the value of $n$ is 1.
