"WebA triple bond forces a linear configuration because of the fact that it is comprised of a sigma and two pi bonds which are rigid, meaning that it cannot rotate. A linear configuration is one where there are no "bends" in the molecular structure of the compound; it keeps going in the same direction. Hope that helps! " - Doubel bodn to triple bdon mechinism
