Q: Which of the following groups is a strong -M group?
Solution: -NO2 is a strong -M group as it withdraws electron density through resonance.
Steps: 4
Step 1: Understand what a -M group is. A -M group (minus mesomeric group) is a group that withdraws electron density from a molecule through resonance.
Step 2: Identify the group in the question. The group we are looking at is -NO2 (nitro group).
Step 3: Analyze how -NO2 behaves. The -NO2 group has a nitrogen atom that can pull electron density away from the rest of the molecule through resonance.
Step 4: Conclude that since -NO2 withdraws electron density effectively, it is classified as a strong -M group.
