I think this must be a mistake, 80 ochem destroyer. do we not make the more substituted double bound in elimination? in here they say not when we remove the cl. any idea? or this is a mistake?
Its because of the cutting tool used. T-butoxide is big and bulky and therefore will make a double bond in the most readily accesible location-the zaitchev.
E2 elimination is usually performed under the conditions of having a strong, bulky base with a less hindered halide, in this case, secondary halide. Therefore a less substituted alkene is formed.
However, if this were a E1 rxn, then a more substituted alkene would form (Zaitsuv Rule).
