Question

Which of the following statements correctly describes the general reactivity of alkynes?

• A. Alkynes are more reactive than alkenes
• B. Alkyne reacts as an electrophile
• C. Unlike alkenes, alkynes do not undergo electrophilic addition reaction
• D. In alkynes, $\pi$-electrons are loosely held, electrophilic attack occur here.

Answer 1

The correct option is D In alkynes, $\pi$-electrons are loosely held, electrophilic attack occur here.

In alkynes, $\pi$-electrons are loosely held, hence, electrophilic attack occur here. So, option (d) is the correct answer.
