The rule that states that if more than one alkene can beformed by an elimination reaction, the more stable alkene is themajor product. In general, the compound that has a more highlysubstituted C=C double bond is more stable due to the electrondonating properties of the alkyl group. The rule is very generaland has many correct examples.

Zaitsev product(s), showing the stereochemistry clearly. If there
is more than one organic product, both products can be drawn in the
same box.the hint:Consider that the reaction is an elimination in the presence of
a relatively small base to give the Zaitsev product, which is the
most stable. Also consider the stereochemistry of the reactant and
that the elimination must be anti-periplanar.
