Chapter 17.8, Problem AQ
Interpretation Introduction

Interpretation: 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 International Union for Pure and Applied Chemistry the name of an alkane ends with ene. Alkenes have a general formula CnH2n 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,

b) Certain cyclic compounds are known to be conformationally similar to carbohydrates, although they are not themselves carbohydrates. One example is Compound C shown below, which could be imagined as adopting four possible conformations. In reality, however, only one of these is particularly stable. Circle the conformation you expect to be the most stable, and provide an explanation to justify your choice. For your explanation to be both convincing and correct, it must contain not only words, but also "cartoon" orbital drawings contrasting the four structures. Compound C Possible conformations (circle one): Дет

For the titration of a divalent metal ion (M2+) with EDTA, the stoichiometry of the reaction is typically: 1:1 (one mole of EDTA per mole of metal ion) 2:1 (two moles of EDTA per mole of metal ion) 1:2 (one mole of EDTA per two moles of metal ion) None of the above
