Concept explainers
(a)
Interpretation:The cis/trans ratio refers to in permethrin needs 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.
(b)
Interpretation: The
Concept Introduction:Permethrin is a synthetic insecticide containing ester group. They are used in commercial clothing and agricultural products. Racemic mixture contains enantiomers in equal amounts and it is optically inactive.
