Q: What is the effect of the +M effect on the stability of a carbocation?

Solution: The +M effect stabilizes the carbocation by donating electron density through resonance.

Steps: 5

Step 1: Understand what a carbocation is. A carbocation is a positively charged carbon atom that has only three bonds instead of four.
Step 2: Learn about the +M effect. The +M effect, or +Mesomeric effect, refers to the ability of certain groups (like -OH, -OCH3, -NH2) to donate electron density to a nearby positive charge through resonance.
Step 3: Recognize how resonance works. Resonance is when electrons can move around in a molecule, creating different structures that are more stable than the original.
Step 4: Connect the +M effect to carbocation stability. When a group with a +M effect is near a carbocation, it can share its electron density with the carbocation, helping to reduce the positive charge.
Step 5: Conclude that the +M effect stabilizes the carbocation. By donating electron density, the +M effect makes the carbocation more stable than it would be without that group.
