Q: How does the presence of a +M group affect the stability of a carbocation?

Solution: A +M group increases the stability of a carbocation by donating electron density through resonance.

Steps: 6

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 +M groups. +M groups are electron-donating groups that can share their electrons with other atoms.
Step 3: Recognize that carbocations are unstable because they have a positive charge. This makes them want to gain more electrons to become stable.
Step 4: Know that +M groups can help stabilize carbocations. They do this by donating electron density to the positively charged carbon.
Step 5: Understand resonance. When a +M group donates electrons, it creates a resonance structure that spreads out the positive charge over multiple atoms, making the carbocation more stable.
Step 6: Conclude that the presence of a +M group increases the stability of a carbocation by providing extra electrons and allowing for resonance.
