Which of the following reactions is/are shown by alkynes?
Correct answer: D. All of these
- A. Hydrogenation
- B. Hydrohalogenation
- C. Hydration
- D. All of these
Explanation
Alkynes are capable of undergoing addition reactions due to the presence of a triple bond with loosely held pi-electrons. This allows for the addition of various molecules such as halogens, hydrogen, and water. Option D is correct because alkynes can indeed undergo all of these addition reactions. Options A, B, and C are incorrect because while alkynes can undergo these reactions to some extent, they are not specific to alkynes and are also observed in other types of compounds.
