Alkynes show _ reactions.
Correct answer: D. Both electrophilic and nucleophilic addition
- A. Neither electrophilic nor nucleophilic addition
- B. Nucleophilic addition only
- C. Electrophilic only
- D. Both electrophilic and nucleophilic addition
Explanation
Alkynes are capable of undergoing both electrophilic addition and nucleophilic addition reactions. The presence of a triple bond in alkynes allows them to react with both electrophiles and nucleophiles. In electrophilic addition, the π electrons of the triple bond act as nucleophiles attacking electrophilic reagents, while in nucleophilic addition, a nucleophile attacks the positively polarized carbon atom in the alkyne. The correct answer option, 'Both electrophilic and nucleophilic addition,' is supported by the fact that alkynes can participate in both types of addition reactions, leading to the formation of various products. The other options are incorrect because alkynes can undergo both types of addition reactions, not just one exclusively.
