Molecular Orbital Theory. considers bonds as localized between one pair of atoms. considers electrons delocalized throughout the entire molecule. creates bonds from overlap of atomic orbitals ( s, p, d …) and hybrid orbitals ( sp, sp2, sp3 …) combines atomic orbitals to form molecular orbitals (σ, σ*, π, π*) forms σ or π bonds. 1. Comment actions. Permalink. I would also greatly appreciate a series on this topic. (Lewis,) VSEPR, Valence Orbitals and MO. In MO theory explaining bonding, anti bonding, and non bonding orbitals in general and how to fill the electrons in the orbitals. Between molecules like N2, O2 and others like HF. Thanks so much!!! The number of molecular orbitals created by hybridization depends on the number of atomic orbitals that are mixed to form them. In forming sp3 hybridized orbitals, four atomic orbitals are mixed, one s and three p. The energy diagram for this process is shown below. The hybridized orbitals are higher in energy than the s By constructing a molecular orbital picture for each of the following molecules, determine whether it is paramagnetic or diamagnetic. a. B 2 b. C 2 c. O 2 d. NO e. CO a. B 2 is paramagnetic because it has two unpaired electrons, one in each of its p orbitals. b. C 2 is diamagnetic because all of its electrons are paired.

Chemistry 2100 In-Class Test 1(A)

The molecular orbital diagram for ClO – is given below: The basis orbitals for Cl are 3s and 3p and for O are 2s and 2p. Z* for O 2s and 2p orbitals are similar so the AOs start at nearly the same energy. For the Cl 3s and 3p orbitals the two Z* values are quite different so the initial energies are more separated.
