Which of the following compounds will be most stable due to resonance?

Which of the following compounds will be most stable due to resonance?

Step 1: Understand what resonance means. Resonance is when electrons can be distributed in different ways in a molecule, which can stabilize it.
Step 2: Identify the compounds in the question. We are looking at compounds that have different groups attached to a benzene ring.
Step 3: Look for electron-withdrawing groups. These groups pull electrons away from the rest of the molecule, which can help stabilize negative charges.
Step 4: Focus on the -NO2 group. The -NO2 (nitro) group is a strong electron-withdrawing group.
Step 5: Determine how the -NO2 group affects stability. It helps stabilize any negative charge through resonance by allowing the charge to be spread out.
Step 6: Compare the stability of the compounds. The compound with the -NO2 group (C6H5NO2) will be the most stable due to its ability to stabilize negative charges through resonance.
