Nettet5. apr. 2024 · For starters, trimethylammonium is about the size of a tert -butyl group. So, expect an A value around 4.9, which is very large. So, put that group equatorial on the ring. Once you do this, you see that there are only 2 hydrogen atoms that are anti-periplanar for an E2 elimination. One is on the axial methyl group (red).

This chapter reviews the Hofmann elimination because of its … NettetStep-1. Explanation of part (a): The process of producing tertiary amines and alkenes from quaternary ammonium is called Hofmann elimination. This process can also be referred to as exhaustive methylation. The Hofmann rule states that the major alkene product is the least substituted and least stable product when it comes to asymmetrical amines. scottish government mask wearing
