Interpretation Introduction
Interpretation: It is assumed by chemist that, an increase of
10K temperature doubles the rate of reaction. The activation energy is calculated for the given temperature to make the given statement correct.
Concept introduction: The energy difference between activated complex and reactants is known as activation energy. The relationship between the rate constant and temperature is given by the Arrhenius equation,
k=Ae−EaRT
To determine: The value of activation energy to make the statement “an increase of
10K temperature doubles the rate of reaction” true for a temperature increases from
25°C to
35°C.

Write the reagents required to bring about each reaction next to the arrows shown.
Next, record any regiochemistry or stereochemistry considerations relevant to the
reaction. You should also record any key aspects of the mechanism, such as forma-
tion of an important intermediate, as a helpful reminder. You may want to keep
track of all reactions that make carbon-carbon bonds, because these help you build
large molecules from smaller fragments. This especially applies to the reactions in…
Provide the reasonable steps to achieve the following synthesis.
