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

Options:

Correct Answer: C6H5NO2

Solution:

C6H5NO2 is most stable due to the strong electron-withdrawing effect of the -NO2 group, which stabilizes the negative charge through resonance.

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.
