NettetThe corresponding designation for the elimination reaction is E2. An energy diagram for the single-step bimolecular E2 mechanism is shown on the right. We should be aware that the E2 transition state is less well defined than is that of S N 2 reactions. More bonds are being broken and formed, with the possibility of a continuum of states in ...

Write short note on Hofmann
The Hofmann rearrangement (Hofmann degradation) is the organic reaction of a primary amide to a primary amine with one fewer carbon atom. The reaction involves oxidation of the nitrogen followed by rearrangement of the carbonyl and nitrogen to give an isocyanate intermediate. The reaction can form a wide range of products, including alkyl and aryl amines.

Think of this as ammonium bromide with two hydrogens replaced by ethyl groups. There is again the possibility of a reversible reaction between this salt and excess ammonia in the mixture. garage door repair flower mound
