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

Options:

Correct Answer: Bromine

Solution:

Bromine, often in the presence of a catalyst like FeBr3, acts as a common electrophile in electrophilic aromatic substitution reactions.

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

Which of the following is a common electrophile 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: Know that electrophilic aromatic substitution reactions involve an aromatic compound reacting with an electrophile.
Step 3: Identify common electrophiles used in these reactions. One common electrophile is bromine (Br).
Step 4: Recognize that bromine often needs a catalyst to help it react with the aromatic compound. A common catalyst for bromine is iron(III) bromide (FeBr3).
Step 5: Conclude that bromine, in the presence of FeBr3, is a common electrophile in electrophilic aromatic substitution reactions.
