What theory provides information concerning both molecular shape and molecular bonding?
Molecular orbital theory(MOT) provides information about both molecular shape and molecular bonding.
Can orbital hybridization theory can describe both the shape and bonding of the molecules?
Orbital hybridization provides information about both molecular bonding and molecular shape.
SiF4 bond type?
:Structure of SiF4 is a regular tetrahedron, any regular geometry has net zero dipole moment as all individual dipole in a molecule cancel the effect of each other. About paramagnetic behaviour of oxygen gas, according to the Molecular Orbital theory oxygen has two unpaired electron in its Pi anti bonding molecular orbital, which is the cause of their paramagnetism.
How do fluorine atom form negative ions?
it depends on the molecular orbital theory
What is the disadvantages of molecular orbital approach?
according to molecular orbital theory{MOT} O+ has bond order 2.5 and O has bond order 2 but actually O is more stable than O+.
Molecular orbital theory is based upon which model of the atom?
Molecular orbital theory determines molecular structure that the electrons are not assigned as individual bonds between atoms, however, are treated as moving under the influence of the nuclei in the whole molecule.
Why molecular orbital theory superior to valence bond theory and VESPR theory?
Superior is a difficult term. The latest versions valence bond theory and molecular orbital theories give similar answers. The simple old versions work from different premises- valence bond assumes localised pair bonds molecular orbital theory is better ate predicting spectroscopic properties. VSEPR is different again and focuses on the geometry around a central atom- and as such is better than both the simple versions of the other theories.
Why is oxygen molecule paramagnetic?
Answer 1) O2 molecule has two unpaired electrons which is only proved by Molecular orbitals theory (M.O.T). the M.O.T may be checked in any standard book of Inorganic chemistry.Answer 2) If you examine the orbital diagram for dioxygen, it contains a SOMO (Singly-Occupied Molecular Orbital) with 2 unpaired electrons. Dinitrogen does not have this. These unpaired electrons contribute to magnetism.
What is meant by magnetic shell?
give Langevins theory of paramagnetism?
What year was the Valence Bond Theory invented?
Gilbert Lewis followed by Linus Pauling who is credited with the quantum mechanical approach, called valence bond theory (distinguishing it from the more recent molecular orbital theory), which is based on Lewis's electron pair bonding theory now taught as Lewis "dot" diagrams.
Why Molecular bond Theory is better than Valence bond theory?
Molecular orbital theory is more recent than Valence bond theory. Both theories have their adherents and recently VB theory has had a renaissance. They both have their strengths. Chemists use both and mix/match. Some very familiar concepts used every day by chemists spring originally from VB theory, electronegativity, hybridisation of atomic orbitals. MO theory has its advocates, an early triumph was the prediction of the paramagnetism of O2 whereas valence bond theory predicted O2 to be diamagnetic. One criticism of VB theory is that it starts from a description of bonds as localised pairs of electrons, whereas in MO all bonds are potentially delocalised.
How does the molecular order structure explain the magnetic properties of oxygen?
Molecular orbital theory predicts that ground state diatomic oxygen has two unpaired electrons (it is a diradical) which occupy its pi orbitals. These unpaired electrons produce a magnetic moment and are responsible for the paramagnetic property of diatomic oxygen.
