Molecular Shapes

61.1K
Molecules have characteristic shapes that are crucial for their function. The arrangement of various electron groups around the central atom dictates their molecular geometry. Electron pairs in the valence shell of a central atom will adopt an arrangement that minimizes repulsions between the electron pairs by maximizing the distance between them. The valence electrons form either bonding pairs, located primarily between bonded atoms, or lone pairs.

What is Organic Chemistry?

87.4K
Organic chemistry is the study of compounds of carbon called organic compounds. Organic compounds either originate from living organisms or are synthesized by chemists. A defining trait of these compounds is the presence of carbon as the principal element, which is bonded to other carbon atoms and other elements such as hydrogen, oxygen, nitrogen, and sulfur. The existence of a wide array of organic molecules is a consequence of carbon atoms’ ability to form up to four strong bonds to...

Polymer Classification: Stereospecificity

3.1K
Polymerization generates chiral centers along the entire backbone of a polymer chain. Accordingly, the stereochemistry of the substituent group has a significant effect on polymer properties. Polymers formed from monosubstituted alkene monomers feature chiral carbons at every alternate position in the polymer backbone. Relative to the predominant orientation of substituents at the adjacent chiral carbons, the polymer can exist in three different configurations: isotactic, syndiotactic, and...

Polymer Classification: Architecture01:14

Polymer Classification: Architecture

3.6K
Polymers are classified as linear or branched on the basis of their chain architecture. The polymer chains in linear polymers have a long chain-like structure with minimal to no branching at all. Even if a polymer features large substituent groups on the monomer, which appear as branches to the skeleton, it is not considered a branched polymer. A branched polymer contains secondary polymer chains that arise from the main polymer chain. The branching occurs when the polymer growth shifts from...

Organic Compounds

56.0K
All living things are formed mostly of carbon compounds called organic compounds. The category of organic compounds includes both natural and synthetic compounds that contain carbon. Although a single, precise definition has yet to be identified by the chemistry community, most agree that a defining trait of organic molecules is the presence of carbon as the principal element, bonded to hydrogen and other carbon atoms. However, some carbon-containing compounds such as carbonates, cyanides, and...

Area of Science:

  • Chemistry
  • Bioinformatics
  • Computational Science

Background:

  • Interdisciplinary scientific collaboration faces communication barriers due to specialized jargon, such as organic chemical nomenclature.
  • Organic chemical nomenclature, while efficient for chemists, presents a steep learning curve for experts in related fields like biology, pharmacology, medicine, computer science, and mathematics.
  • This communication gap can hinder productivity and introduce errors in diverse research teams.

Purpose of the Study:

  • To develop a user-friendly web tool, SmartChemist, to facilitate clear communication of chemical structures among scientists with varying backgrounds.
  • To bridge the knowledge gap regarding organic chemical nomenclature in interdisciplinary research settings.

Main Methods:

  • The SmartChemist tool accepts molecular files or Simplified Molecular Input Line Entry System (SMILES) strings as input.
  • It employs a comprehensive database of over 40,000 curated patterns to identify specific molecular substructures.
  • The tool displays identified substructures, including cyclic structures, functional groups, and biologically relevant molecules, prioritizing the most specific matches.
