Major stereo chemical product should be found for the given E2 elimination reactions. Concept introduction: E2 elimination reaction: E2 elimination occurs in a compound when the leaving group is antiperiplaner to the proton in presence of strong base. If the base is bulky in nature, least substituted alkene is favorable and the base is not bulky and stronger in nature, most substituted alkene is the favorable product. For E2 elimination reaction, proton should be present at β position to the leaving group in antiperiplaner way.
