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. http://www.chem.ucla.edu/~harding/IGOC/E/electron_density.html bing rewards reddit this or that
