Which of the following statements correctly describes the general reactivity of alkynes? A) An alkyne is an electron-rich molecule and therefore reacts as a nucleophile.B) The σ bonds of alkynes are higher in energy than the π bonds and are thusmore reactive. C) Unlike alkenes, alkynes fail to undergo electrophilic addition reactions. D) Alkynes are generally more reactive than alkenes. E) Alkynes react as electrophiles, whereas alkenes reacts as nucleophiles.
