Question: Which of the following compounds will not undergo electrophilic substitution?

Options:

Correct Answer: Nitrobenzene

Solution:

Nitrobenzene will not undergo electrophilic substitution readily because the nitro group is a strong deactivator and meta-director.

Which of the following compounds will not undergo electrophilic substitution?

Which of the following compounds will not undergo electrophilic substitution?

Step 1: Understand what electrophilic substitution means. It is a reaction where an electrophile replaces a hydrogen atom in an aromatic compound.
Step 2: Identify the compounds in the question. We need to focus on the one that does not undergo this reaction.
Step 3: Learn about the nitro group (-NO2). It is a functional group that can be attached to benzene rings.
Step 4: Recognize that the nitro group is a strong deactivator. This means it makes the benzene ring less reactive towards electrophiles.
Step 5: Understand that the nitro group directs new substituents to the meta position rather than the ortho or para positions.
Step 6: Conclude that because the nitro group deactivates the ring and directs substitution to the meta position, nitrobenzene will not undergo electrophilic substitution readily.
