What is the major alkene formed in the following Hofmann

Hofmann elimination is an elimination reaction of an amine to form alkenes. The least stable alkene (the one with the least number of substituents on the carbons of the double bond), called the Hofmann product, is formed.

NettetThe Zaitsev’s and Hoffman’s rules demonstrate the principle of regioselectivity in elimination reactions. Regioselective means that the reaction selectively produces one … NettetThis is illustrated for 2-bromobutane by the energy diagram on the right. The propensity of E2 eliminations to give the more stable alkene product also influences the distribution of product stereoisomers. In the elimination of 2-bromobutane, for example, we find that trans-2-butene is produced in a 6:1 ratio with its cis-isomer.
