NettetWhat is Hofmann Elimination? The Hofmann Elimination reaction follows the Hofmann alkene synthesis rule. Usual elimination reactions follow Zaitsev’s rule but for bulky leaving groups like -N(CH 3) 3 +, Hofmann alkene synthesis rule is applied and E 2 elimination gives the least substituted alkene as the major product. The amines (1 0, … NettetThe elimination proceeds via a five-membered cyclic transition state and it is a one-step, concerted internal elimination during which, the amine oxide serves both as a base and a leaving group. These types of reactions are also referred to as Ei (elimination intramolecular). In general, the reaction is unimolecular and follows the same rate ... engine matching numbersNettetIf you have a 3° carbon, the substitution reaction will be SN1. For 1° and 2° carbons, the substitution will be SN2. It is the strength of the base that determines the type of elimination. If you have a strong base, you will get E2 elimination. If you have a weak base, you will get E1 elimination from 3° substrates and probably no reaction ... engine mathematics
