Quizplus · Accepted Answer

A π bond is formed by the overlap of two atomic orbitals side by side, resulting in the sharing of two electrons. In the given molecule, there are two double bonds (C=C) and one triple bond (C≡C). Each double bond contains one π bond, and the triple bond contains two π bonds. Therefore, there are a total of 2 + 2 = 4 π bonds in the molecule. However, the question specifically asks for the number of π bonds, not the total number of multiple bonds. Therefore, the correct answer is C) 2.
