Chemistry
As a result, an alkene is formed as a product Since b-hydrogen
atom is involved in elimination, it is often called bbbbb-elimination If there is possibility of formation of more than one alkene due to
the availability of more than one b-hydrogen atoms, usually one alkene
is formed as the major product These form part of a pattern first
observed by Russian chemist, Alexander Zaitsev (also pronounced as
Saytzeff) who in 1875 formulated a rule which can be summarised as
“in dehydrohalogenation reactions, the preferred product is that
alkene which has the greater number of alkyl groups attached to the
doubly bonded carbon atoms
