Which of the following is a characteristic reaction of alkynes?

Step 1: Understand what alkynes are. Alkynes are a type of hydrocarbon that contain at least one triple bond between carbon atoms.
Step 2: Learn about characteristic reactions. Characteristic reactions are specific types of chemical reactions that are typical for a certain group of compounds.
Step 3: Identify the reactions mentioned: hydrogenation, hydrohalogenation, and halogenation.
Step 4: Hydrogenation is when hydrogen is added to the alkyne, converting it into an alkene or alkane.
Step 5: Hydrohalogenation is when hydrogen halides (like HCl or HBr) react with the alkyne, adding halogen atoms.
Step 6: Halogenation is when halogens (like Cl2 or Br2) react with the alkyne, adding halogen atoms across the triple bond.
Step 7: Conclude that all these reactions (hydrogenation, hydrohalogenation, and halogenation) are characteristic of alkynes.
