Common questions

What is the MO electron configuration of CO?

What is the MO electron configuration of CO?

Molecular Orbital diagram of Carbon monoxide molecule (CO): CO =σ1s2,σ*1s2,σ2s2,σ*2s2, σ2px2, π2py2= π2pz2.

Which of Molecular Orbital has the highest energy in CO?

Which molecular orbital has highest energy in CO molecule?

  • The HOMO orbitals are the highest energy molecular orbitals occupied by electrons.
  • The highest occupied molecular orbital (HOMO) in CO molecule is 3 σ.

What is the bond order for CO?

The bond order of CO is 3 as oxygen shares two of its electrons with carbon and makes a dative bond filling it’s shell.

Why is CO called PI acid ligand?

Carbon monoxide is an example of a pi-acid ligand (CO). Due to empty pi orbitals and a good sigma donor, CO is a good pi acceptor or Lewis acid.

What is Mo diagram of CO?

Carbon monoxide MO diagram. Carbon monoxide is an example of a heteronuclear diatomic molecule where both atoms are second-row elements. The valence molecular orbitals in both atoms are the 2s and 2p orbitals. The molecular orbital diagram for carbon monoxide (Figure 5.3.

How do you write Mo configuration?


  1. Find the valence electron configuration of each atom in the molecule.
  2. Decide if the molecule is homonuclear of heteronuclear.
  3. Fill molecular orbitals using energy and bonding properties of the overlapping atomic orbitals.
  4. Use the diagram to predict properties of the molecule.

What is an orbital energy diagram?

Orbital diagrams are a pictorial description of electrons in an atom. In order to figure out where electrons go in an atom we have to follow 3 main rules. The first one being the Auf Bau Principle, the Auf Bau Principle states that each electron occupies the lowest energy orbital available.

Does CO and NO have same bond order?

So, the bond order of a nitric oxide molecule is 2.5. So, from the above discussion now we know that the bond order of carbon monoxide and nitric oxide molecules is 3 and 2.5 respectively. So, the correct answer is “Option B”.

How do you find the bond order of CO2?

What is the bond order of CO2? Bond Order = number of bonding electrons – number of antibonding electrons/2. For CO2, there is a total of 16 electrons, 8 of which are antibonding electrons. Bond order of CO2 is 2.

IS NO+ a pi acceptor?

This tells us how much of the electron density is on the metal and how much is on the ligand, and even which orbitals it ends up in Table 1. o NO+ is one of the strongest π-acceptors, but σ-donation is poor o CN- is a poor π-acceptor however it is a strong σ-donor o we can deduce that if the energy of the π* orbitals …

How is MO theory used to predict molecular structure?

MO Theory. • LCAO-MO Theory is a simple method for predicting the approximate electronic structure of molecules. • Atomic orbitals must have the proper symmetry and energy to interact and form molecular orbitals. • Photoelectron spectroscopy provides useful information on the energies of atomic orbitals.
