What is homonuclear diatomic molecules?

What is homonuclear diatomic molecules?

Homonuclear molecules, or homonuclear species, are molecules composed of only one element. Homonuclear molecules may consist of various numbers of atoms, depending on the element’s properties. Homonuclear diatomic molecules include hydrogen (H2), oxygen (O2), nitrogen (N2) and all of the halogens.

How do you write the electronic configuration of a diatomic molecule?

Thus we would expect a diatomic molecule or ion containing seven electrons (such as Be2+) would have the molecular electron configuration (σ1s)2 ( σ 1 s ) 2 (σ∗1s)2 ( σ 1 s ∗ ) 2 (σ2s)2 ( σ 2 s ) 2 (σ∗2s)1 ( σ 2 s ∗ ) 1 .

What is the bond order of p2?

The bond order of P2 is 3.

Which is most stable homonuclear diatomic molecule?

Hydrogen, nitrogen, and oxygen are stable homonuclear diatomic molecules.

What is the difference between homonuclear and heteronuclear molecules?

The key difference between homonuclear and heteronuclear diatomic molecules is that homonuclear diatomic molecules contain two atoms of the same element whereas heteronuclear diatomic molecules contain two atoms of different elements.

What is Mo configuration?

Molecular orbital (MO) theory describes the behavior of electrons in a molecule in terms of combinations of the atomic wave functions. The resulting molecular orbitals may extend over all the atoms in the molecule.

Which of the following is the correct electron configuration for c2?

The electronic configuration of carbon is 1s2 2s2 2p2.

Why B2 is more stable than Li2?

Why is B2 more stable than Li2? Both B2 and Li2 have bond order equal to 1. Moreover, Li2 has only 2 electrons in the antibonding molecular orbital while B2 has 4 electrons in the antibonding molecular orbital.

Why do homonuclear diatomic molecules not show vibrational spectra?

Answer: homonuclear diatomic molecule like H2, O2, N2 etc. which have only stretching motion/ vibrations and no bending motion/vibrations, the dipole moment does not change during vibration. Hence these molecules do not give vibration spectra i.e. they are said to be infrared-inactive.

How can a homonuclear diatomic molecule decrease its bonding?

Note: The Bond Order of a Homonuclear Diatomic Molecule can be decreased by removing electron from a Bonding Molecular Orbital or by adding electrons to AntiBonding Molecular Orbital. The electronic configuration of nitrogen atom is 1s 2 2s 1 2p x1 2 y1 2p z1 and N 2 molecule has 14 electrons.

Which is the molecular orbital configuration of he 2 +?

The molecular orbital electronic configuration of the molecule is The value of bond order states that He 2+ is stable. Its bond dissociation energy is 242 kJ mol -1. Therefore, the molecule is paramagnetic and the same has been experimentally observed also.

How are the orbitals of diatomic molecules related?

Figure 8.4. 1: Molecular orbital energy level diagram for homonuclear diatomic molecules showing the correlation of the molecular orbitals with the atomic orbitals of the separated atoms. The schematic representation of the molecular orbitals is to illustrate their general forms and nodal properties (the nodes are indicated by dashed lines).

Which is a homonuclear molecule with only two atoms?

Homonuclear Diatomic Molecules are those molecules which are made up of single nucleus and consist of only two atoms. In this article, we will be discussing about some Homonuclear Diatomic Molecules of first and second rows of periodic table, about their bond order, magnetic behavior etc.
