Web4 de mai. de 2013 · 6,630 3 30 60. 2. Actually, the electron density of the "second" and "third" bonds has a node at the center line. Pi and delta bonds always do. So a triple bond has no more electron density along the center line that a single bond. It will have multiple local maximae of lesser density, and probably one global maxima; the center line.
