An antibonding orbital is a molecular orbital containing an electron outside the region between the two nuclei. As two atoms approach each other, their electron orbitals begin to overlap. This overlap forms a molecular bond between the two atoms with its own molecular orbital shape.
Sigma bonds are formed only by s orbitals and pi bonds are formed only by p orbitals. B. Sigma bonds are formed only by p orbitals and pi bonds are formed only by s orbitals. C. Sigma bonds are formed by either s or p orbitals, pi bonds are formed only by p orbitals. D. Sigma and pi bonds are formed by either s or p orbitals. 13. According to VSEPR theory, repulsion between electron pairs in a valence shell decreases in. the order. A. lone pair-lone pair > lone pair-bond pair > bond pair-bond pair.
