Interpretation Introduction

Interpretation: The correct reaction condition which could conceivably be used to create ester linkage in the given compounds ahould be determined.

Concept introduction:

Permethrin and bifenthrin are the synthetic pyretherenoids now in common use in household and agricultural products.

Their structure is given below,

In Fischer esterification, a carboxylic acid is reacted with an alcohol in the presence of an acid catalyst, such as concentrated sulfuric acid.

Fischer esterification can be represented as follows,

Acid chlorides are organic compound and they have functional group $RCOCl$.

Acid chlorides are most often prepared by treating a carboxylic acid with thionyl chloride.

Acid chlorides on reaction with alcohol give esters.

$\underset{Acidchloride}{RCOCl}+\underset{Alcohol}{R\text{'}OH}\to \underset{Ester}{RCOOR\text{'}}+HCl$
