Question 9 1 pts Which of the following statements describes the reactivity of alkynes? An alkyne is an electron-rich molecule and therefore reacts as a nucleophile. When a symmetrical internal alkyne reacts with HBr, two products are formed. Unlike alkenes, alkynes fail to undergo electrophilic addition reactions The o bonds of alkynes are greater in energy than the rt bonds and, therefore, are more reactive Alkynes react as electrophiles, whereas alkenes react as nucleophiles What is...
