Covalent Bonding and Lewis Structures

Covalent Bonding and Lewis Structures

Compared to ionic bonds, which results from the transfer of electrons between metallic and nonmetallic atoms, covalent bonds result from the mutual attraction of atoms for a “shared” pair of electrons.

Radical Formation: Homolysis

Radical Formation: Homolysis

A bond is formed between two atoms by sharing two electrons. When this bond is broken by supplying sufficient energy, either two electrons can be taken up by one atom forming ions by the cleavage called heterolysis, or the two electrons are shared by two atoms, with one each creating radicals by the cleavage called homolysis.

Hybridization of Atomic Orbitals I

Hybridization of Atomic Orbitals I

The mathematical expression known as the wave function, ψ, contains information about each orbital and the wavelike properties of electrons in an isolated atom. When atoms are bound together in a molecule, the wave functions combine to produce new mathematical descriptions that have different shapes. This process of combining the wave functions for atomic orbitals is called hybridization and is mathematically accomplished by the linear combination of atomic orbitals. The new orbitals that...

Exceptions to the Octet Rule

Exceptions to the Octet Rule

Many covalent molecules have central atoms that do not have eight electrons in their Lewis structures. These molecules fall into three categories:

Hydrogen Bonds

Hydrogen Bonds

A hydrogen bond is formed when a weakly positive hydrogen atom already bonded to one electronegative atom (for example, the oxygen in the water molecule) is attracted to another electronegative atom from another polar molecule, such as water (H2O), hydrogen fluoride (HF), or ammonia (NH3). The huge electronegativity difference between the H atom (2.1) and the atom to which it is bonded (4.0 for an F atom, 3.5 for an O atom, or 3.0 for an N atom), combined with the very small size of an H atom...

Background:

Noble gases, including radon, are typically inert.
Understanding the chemical properties of heavy noble gas compounds is an active research area.
Radon hydrides (HRnY) represent a class of compounds with potential for unique chemical behavior.

Purpose of the Study:

To investigate the stability and bonding characteristics of radon hydrides (HRnY).
To determine the feasibility of synthesizing and identifying these compounds.
To explore the decomposition pathways of radon hydrides.

Main Methods:

Utilizing quantum chemical calculations.
Employing gradient-corrected density functional theory at the BP86 level.
Using TZ2P basis sets for high accuracy.

Main Results:

All studied radon hydrides (HRnY) exist as bound equilibrium structures.
These species are metastable concerning decomposition into radon and hydrogen halide (HRnY → Rn + HY).
The reaction leading to individual atoms (HRnY → H + Rn + Y) is endothermic, indicating a degree of stability.

Conclusions:

Radon hydrides are theoretically stable enough to be identified.
Experimental identification in noble-gas matrices is a plausible approach.
The study provides valuable insights into the chemistry of heavy noble gas compounds.
