Q
Q: Which of the following groups shows +M effect?
Solution:
The -OCH3 group shows +M effect as it donates electrons through resonance.
Steps: 5
Show Steps
Step 1: Understand what +M effect means. +M effect refers to the +Mesomeric effect, where a group donates electrons through resonance.
Step 2: Identify the group in the question. The group we are looking at is -OCH3 (methoxy group).
Step 3: Analyze the -OCH3 group. The oxygen atom in -OCH3 has lone pairs of electrons that can be shared with the rest of the molecule.
Step 4: Determine if the -OCH3 group can donate electrons. Yes, it can donate electrons through resonance, which is characteristic of the +M effect.
Step 5: Conclude that the -OCH3 group shows +M effect because it donates electrons through resonance.
