State the Valence Bond Theory
a quantum mechanical
description of bonding that pictures covalent
bond formation as the overlap of two singly

Define a sigma bond
a covalent bond formed by
head-on overlap of orbitals in which the shared
electrons are centered about the axis between the
two nuclei
3 of 17
Define a pi bond
a covalent bond formed by sideways overlap of orbitals in which shared electrons
occupy a region above and below a line connecting the two nuclei

State the Molecular orbital theory
a quantum mechanical description of bonding in which electrons
occupy molecular orbitals that belong to the
entire molecule rather than to an individual atom
14 of 17
Define a molecular orbital
a wave function whose
square gives the probability of finding an electron
within a given region of space in a molecule
