Question: Which of the following is a common electrophile used in electrophilic aromatic substitution reactions?

Options:

Correct Answer: Bromine

Solution:

Bromine is a common electrophile used in electrophilic aromatic substitution, often activated by a Lewis acid.

Which of the following is a common electrophile used in electrophilic aromatic substitution reactions?

Which of the following is a common electrophile used in electrophilic aromatic substitution reactions?

Step 1: Understand what an electrophile is. An electrophile is a species that seeks electrons and can react with electron-rich areas, like aromatic rings.
Step 2: Learn about electrophilic aromatic substitution (EAS). This is a reaction where an electrophile replaces a hydrogen atom on an aromatic ring.
Step 3: Identify common electrophiles used in EAS. One common electrophile is bromine (Br).
Step 4: Know that bromine often needs help to react with the aromatic ring. This is done by using a Lewis acid, which activates the bromine.
Step 5: Conclude that bromine, when activated, is a common electrophile in electrophilic aromatic substitution reactions.
