10 Questions
What is the role of NaOEt in the given reaction?
It acts as a base.
Why does the E2 reaction rate increase in the following order: F < Cl < Br < I?
Due to the increasing leaving group ability of the halogens.
What is the significance of the solvent EtOH in the given E2 reaction?
It provides a polar medium that facilitates the reaction.
Why is the E2 reaction rate of PhCH2CH2I significantly faster than PhCH2CH2Br?
Due to the better leaving group ability of iodide compared to bromide.
What is the relationship between the leaving group ability of the halogens and the E2 reaction rate?
An increase in leaving group ability correlates with an increase in E2 reaction rate.
What is the trend in E2 reaction rates observed in the given substrates?
The trend in E2 reaction rates is F < Cl < Br < I.
How does the reaction rate of PhCH2CH2Br compare to that of PhCH2CH2Cl?
The reaction rate of PhCH2CH2Br is about 60 times faster than that of PhCH2CH2Cl.
What is the relative rate of the E2 reaction of PhCH2CH2I compared to PhCH2CH2Br?
The E2 reaction rate of PhCH2CH2I is about 6400 times faster than that of PhCH2CH2Br.
What is the approximate percentage of the E2 reaction rate of PhCH2CH2Br compared to PhCH2CH2Cl?
The E2 reaction rate of PhCH2CH2Br is approximately 60% of the rate of PhCH2CH2Cl.
What is the relative order of reactivity of the halogenated substrates in the E2 reaction?
The order of reactivity is I > Br > Cl > F.
Compare the reaction rates of different substrates in an E2 reaction with NaOEt as the base and EtOH as the solvent. Identify the trends and factors affecting the reaction rates.
