Structural Isomerism

Structural Isomerism

Isomerism in Complexes
Isomers are different chemical species that have the same chemical formula. Structural isomerism of coordination compounds can be divided into two subcategories, the linkage isomers and coordination-sphere isomers.
Linkage isomers occur when the coordination compound contains a ligand that can bind to the transition metal center through two different atoms. For example, the CN− ligand can bind through the carbon atom or through the nitrogen atom. Similarly, SCN− can...

Isomerism

Isomerism

Isomers are molecules with the same molecular formula but different structural arrangements. Isomers can be further classified into constitutional isomers and stereoisomers. Constitutional isomers differ in the connectivity of their constituent atoms. For example, 2-butanol and diethyl ether are constitutional isomers, as they have the same chemical formula, C4H10O, but differ in the connectivity of the carbon and oxygen atoms. Constitutional isomers have different physical and chemical...

Isomerism in Alkenes

Isomerism in Alkenes

Alkenes like 1-butene and 2-butene exhibit constitutional isomerism, as they differ in the position of the double bond. Further, 2-butene exhibits stereoisomerism and exists as two distinct compounds differing in spatial arrangement.
An isomer is called cis-2-butene when the methyl groups are on the same side of the double bond, and the other stereoisomer, in which methyl groups are on the opposite side of the double bond, is called trans-2-butene. The cis and trans stereoisomers are not...

Polymers

Polymers

The word polymer is derived from the Greek words “poly” which means “many” and “mer” which means “parts”. Polymers are long chains of molecules composed of repeating units of smaller molecules, known as monomers. They either occur naturally, such as DNA and proteins, or can be constructed synthetically, like plastics. They have varied structural characteristics, such as linear chains, branched chains, or complex networks, that contribute to the...

Proteins: From Genes to Degradation

Proteins: From Genes to Degradation

Within a biological system, the DNA encodes the RNA, and the nucleotide sequence in the RNA further defines the amino acid sequence in the protein. This is referred to as “The Central Dogma of Molecular Biology” - a term coined by Francis Crick. Central dogma is a firm principle in biology that defines the flow of genetic information within any life form. The two fundamental steps in central dogma are - transcription and translation.
Transcription is the synthesis of RNA...

Background:

Hydrocarbon polymers are widely used but challenging to degrade due to their chemical inertness.
Low-energy degradation processes for polymers are difficult to achieve.
Understanding polymer degradation mechanisms is crucial for environmental applications.

Purpose of the Study:

To investigate a novel method for accelerating hydrocarbon polymer degradation.
To explore the relationship between polymer spatial arrangement and degradation ease.
To propose spatial isomerization as a strategy for enhanced polymer degradation.

Main Methods:

Utilized first-principles calculations to model polymer degradation reactions.
Analyzed the energy barriers associated with different polymer spatial arrangements (isotactic, atactic, syndiotactic).
Calculated synthesis rates for various polymer structures to guide experimental efforts.

Main Results:

Demonstrated that the spatial arrangement of polymers significantly impacts their degradation energy barrier.
Found that isotactic and most atactic polymer structures degrade more readily than syndiotactic structures.
Proposed spatial isomerization as a viable method to facilitate polymer degradation.

Conclusions:

Spatial isomerization offers a promising route to enhance the degradation of hydrocarbon polymers.
The findings provide a theoretical basis for designing polymers with controlled degradation properties.
This research paves the way for developing more effective polymer degradation strategies.
