Solution

Solution Steps

Step 1: Understanding Vicinal Dihalides and Vinyl Halides

Vicinal dihalides are compounds where two halogen atoms are attached to adjacent carbon atoms in a carbon chain. Vinyl halides, on the other hand, have a halogen atom directly attached to a carbon-carbon double bond.

Step 2: Reaction of Alkenes with Halogens

When an alkene reacts with a halogen (such as \( \text{Cl}_2 \) or \( \text{Br}_2 \)), the halogen atoms add across the double bond, resulting in a vicinal dihalide. This is a straightforward reaction that occurs in one step.

Step 3: Formation of Vinyl Halides

Vinyl halides are typically not formed directly from alkenes in a single step. They are usually synthesized through other methods, such as dehydrohalogenation of dihalides or halogenation of alkynes.
