Which of the following reactions can be used to prepare alkynes?

Correct Answer: Dehydrohalogenation of alkyl halides

Step 1: Understand what alkynes are. Alkynes are hydrocarbons that contain at least one triple bond between carbon atoms.
Step 2: Know what alkyl halides are. Alkyl halides are organic compounds that contain a carbon atom bonded to a halogen (like chlorine, bromine, or iodine).
Step 3: Learn about dehydrohalogenation. This is a chemical reaction where a hydrogen atom and a halogen atom are removed from an alkyl halide.
Step 4: Realize that when you remove a hydrogen and a halogen from an alkyl halide, you can form a triple bond between carbon atoms, resulting in an alkyne.
Step 5: Conclude that the dehydrohalogenation of alkyl halides is a method to prepare alkynes.
