actually , configuration of C₂ molecule is σ1s² , σ*1s² , σ2s², σ*2s² , π2py² ≈ π2pz²
Here, you see that outermost electrons of C₂ molecule { e.g., π2py² ≈ π2pz²} is 4 . And it belongs to π molecular orbitals . Also you know in bond formation only valance electrons or outermost electrons participate . Hence, in C₂ molecule only π bond exists and number of pi bond = 2
