According to molecular orbital theory, what is an antibonding orbital? Check all that apply. An antibonding orbital is formed when two atomic orbitals destructively interfere with one another An antibonding orbital is usually higher in energy than the two separated atoms and has a node in the internuclear region. An antibonding orbital is usually higher in energy than the two separated atoms and has no nodes in the internuclear region. An antibonding orbital is usually lower in energy than the...
