Mechanism (show a mechanism using curved arrows..)

Problem # 334

Let's go over how a carbocation can form from an alkene.

Use curved arrows to show the two carbocations that can from from 1-methylcyclohexene.

Solution

3° carbocations are more stable than 2º carbocations, so only the 3º carbocation is formed.

Problem # 324

Using curved hooks, draw a mechanism for the free radical bromination reaction shown below.

Solution

Note that the radical will form on the 3° carbon only, as this is the most stable radical.
