choose the following true statement. group of answer choices a triple bond may consist of one sigma bond and two pi bonds or of two sigma bonds and one pi bond. a carbon atom involved in only single bonds may not be sp2 hybridized. a pi bond can hold 4 electrons, two above and two below the sigma-bond axis. a sigma bond is a bond resulting from side-to-side overlap of atomic orbitals. a pi bond is a bond resulting from side-to-side overlap of atomic orbitals.
