Ionic Bonds

Ionic Bonds

When atoms gain or lose electrons to achieve a more stable electron configuration they form ions. Ionic bonds are electrostatic attractions between ions with opposite charges. Ionic compounds are rigid and brittle when solid and may dissociate into their constituent ions in water. Covalent compounds, by contrast, remain intact unless a chemical reaction breaks them.Opposing Charges Hold Ions Together in Ionic CompoundsIonic bonds are reversible electrostatic interactions between ions with...

Valence Bond Theory

Valence Bond Theory

Coordination compounds and complexes exhibit different colors, geometries, and magnetic behavior, depending on the metal atom/ion and ligands from which they are composed. In an attempt to explain the bonding and structure of coordination complexes, Linus Pauling proposed the valence bond theory, or VBT, using the concepts of hybridization and the overlapping of the atomic orbitals. According to VBT, the central metal atom or ion (Lewis acid) hybridizes to provide empty orbitals of suitable...

Chemical Bonds

Chemical Bonds

Atoms participate in a chemical bond formation to acquire a completed valence-shell electron configuration similar to that of the noble gas nearest to it in atomic number. Ionic, covalent, and metallic bonds are some of the important types of chemical bonds. Bond energy and bond length determine the strength of a chemical bond.
Types of Chemical Bonds
An ionic bond is formed due to electrostatic attraction between cations and anions. Often, the ions are formed by the transfer of electrons from...

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.

Background:

Dissociative electron attachment (DEA) is a fundamental process involving electron-molecule interactions.
Temporary negative ion states play a crucial role in DEA, influencing bond breaking.
Understanding factors that enhance DEA cross sections is vital for molecular science.

Purpose of the Study:

To investigate the enhancement of bond breaking in chloroalkenes via DEA.
To determine the influence of a second, longer-lived temporary negative ion state on DEA.
To elucidate the relationship between anion state mixing and bond dissociation.

Main Methods:

Studied a series of chloroalkenes with varying distances between C-Cl and C==C bonds.
Analyzed the cross sections for bond breaking through DEA.
Investigated the role of temporary negative ion state mixing and lifetimes.

Main Results:

The cross section for bond breaking is significantly enhanced by a remote, longer-lived temporary negative ion state.
Anion state mixing determines the cross sections, with wave function coefficients indicating electron localization probability.
The composite anion state lifetime is linked to mixing coefficients and individual resonance lifetimes.

Conclusions:

Remote anion states can effectively enhance DEA-induced bond breaking.
The mixing of anion states provides a mechanism to control electron localization and bond dissociation.
These findings offer insights into electron-induced DNA strand breaks.
