The correct sterochemical descriptor for the alkenes in permethrin and bifentrin has to be determined. Concept introduction: Alkenes are one of the important types of hydrocarbon which have at least one carbon-carbon double bond ( C = C ). According to the I nternational U nion for P ure and A pplied C hemistry the name of an alkane ends with ene. Alkenes have a general formula C n H 2 n where n is the number of carbon atom. E-Z designators are used as like cis-trans terminology for non-similar groups attached alkenes. In E-Z designations, the groups attached to vinylic positions are checked by their priority on the basis of higher molecular weight . If the higher priority groups are on the same sides , then the configuration is designated as Z . If the higher priority groups are on the opposite sides , then the configuration is designated as E. Permethrin and bifenthrin are the synthetic pyretherenoids now in common use in household and agricultural products. Their structure is given below,
