(a) Interpretation: The cis/trans ratio refers to in permethrin is to be predicted. Concept Introduction: Permethrin is a synthetic insecticide containing ester group. They are used in commercial clothing and agricultural products. In cis-isomer, the atom or groups linked to the ring are on the same side of the ring or double bond. In trans-isomer, the atom or groups linked to a ring are on the opposite sides of the ring or double bond.
