Questions & Step-by-Step Solutions
Which of the following is an example of a -M effect?
Step 1: Understand what a -M effect is. The -M effect refers to the ability of certain groups to withdraw electron density from a molecule through resonance.
Step 2: Identify the -NO2 group. The -NO2 group is a nitro group that can affect the electron density in a molecule.
Step 3: Learn how the -NO2 group works. The -NO2 group pulls electron density away from the rest of the molecule, which is what we mean by 'withdrawing' electron density.
Step 4: Connect the -NO2 group to the -M effect. Since the -NO2 group withdraws electron density through resonance, it is an example of a -M effect.
