Molecular orbitals issue from the league of ultimate orbitals. Acetylene, HC = CH, has a triple compact betwixt the carbon atoms (individual sigma compact and span pi compacts). Assume that complete of the compacting is the issue of the overlap of p orbitals. Sketch (with fit shading) and mark the overlap regions (cartoons of Phi) of p orbitals that contrive the compacting molecular orbitals on the forthcoming co-linear x axes. a. The sigma compact. b. Individual pi compact. C. The other pi compact.
