- In electrophilic aromatic substitution, a group attached to the aromatic ring does not affect ring reactivity. A.RightB.FalseSome of the groups pre-bonded to an aromatic ring cause electrophilic aromatic substitution to occur mainly at the ortho and para sites. Others lead to the meta location. Is that true or false?True or false? Some of the groups pre-bonded to an aromatic ring cause electrophilic aromatic substitution to occur mainly at the ortho and para sites. Some lead to the meta location.
- In an electrophilic aromatic substitution, which group is more deactivating: -Cl or -CO-CH2-CH3? Explain the reason.Which of the following would be LEAST reactive for electrophilic aromatic substitution?Predict the site on each molecule that is most likely to undergo electrophilic aromatic substitution.
- What is the driving force for losing a proton as the last step in electrophilic aromatic substitution? To neutralize the base that is present To make room for the electrophile To make the ring more reactive To rearomatize the ring systemGive a clear explanation handwritten answer....given below some compounds give the rank most reactive to least reactive in an electrophilic aromatic substitution reactionFluoride ion is usually a poor leaving group because it is not very polarizable. Fluorideserves as the leaving group in the Sanger reagent (2,4-dinitrofluorobenzene), used inthe determination of peptide structures (Chapter 24). Explain why fluoride works as aleaving group in this nucleophilic aromatic substitution, even though it is a poor leavinggroup in the SN1 and SN2 mechanisms.
