Organic Chemistry Animations ChemTube3D Climate prediction INRS Organic Chemistry Introduction - What Organic Chemists Do By Anne Marie Helmenstine, Ph.D. Updated April 05, 2016. Organic chemistry is more than simply the study of carbon or the study of chemicals in living organisms. Take a look at what organic chemistry is, why it is important, and what organic chemists do. What Is Organic Chemistry? Organic chemistry is the study of carbon and the study of the chemistry of life. Why Is Organic Chemistry Important? Organic chemistry is important because it is the study of life and all of the chemical reactions related to life. continue reading below our video What Does an Organic Chemist Do? An organic chemist is a chemist with a college degree in chemistry.
The ChemCollective Protein Data Bank A Structural View of Biology This resource is powered by the Protein Data Bank archive-information about the 3D shapes of proteins, nucleic acids, and complex assemblies that helps students and researchers understand all aspects of biomedicine and agriculture, from protein synthesis to health and disease. As a member of the wwPDB, the RCSB PDB curates and annotates PDB data. The RCSB PDB builds upon the data by creating tools and resources for research and education in molecular biology, structural biology, computational biology, and beyond. Use this website to access curated and integrated biological macromolecular information in the context of function, biological processes, evolution, pathways, and disease states.

Nomenclature IUPAC Bienvenue à la page de l'assistant IUPAC. Cette page et les suivantes sont destinées à vous aider dans la nomenclature des composés organiques. Le contenu de ces pages se base sur les principes essentiels de nomenclature organique repris dans l'édition 1979(1) des règles de la nomenclature IUPAC et dans le livre reprenant les recommandations de 1993(2). For those interested, an English page will be available soon. Conventions / Glossaire Vous explique entre autre l'usage de la ponctuation, des préfixes et autres parenthèses. Hydrogènes Indiqués ou Ajoutés Précise quand il est nécessaire d'indiquer les atomes d'hydrogène dans le nom. Types de nomenclature Reprend brièvement les différentes nomenclatures IUPAC en usage. Tableau des classes fonctionnelles Types de fonctions utilisés en nomenclature radico-fonctionnelle en préfixes ou en suffixes. Tableau des groupes caractéristiques Noms des groupes fonctionnels utilisés dans la nomenclature substitutive en tant que préfixes et/ou suffixes.

Molecular orbital Complete acetylene (H–C≡C–H) molecular orbital set. The left column shows MO's which are occupied in the ground state, with the lowest-energy orbital at the top. The white and grey line visible in some MO's is the molecular axis passing through the nuclei. The orbital wave functions are positive in the red regions and negative in the blue. The right column shows virtual MO's which are empty in the ground state, but may be occupied in excited states. Overview A molecular orbital (MO) can be used to represent the regions in a molecule where an electron occupying that orbital is likely to be found. Formation of molecular orbitals Molecular orbitals arise from allowed interactions between atomic orbitals, which are allowed if the symmetries (determined from group theory) of the atomic orbitals are compatible with each other. Qualitative discussion Linear combinations of atomic orbitals (LCAO) Molecular orbitals were first introduced by Friedrich Hund and Robert S.
iSUSTAIN Green Chemistry Index chimie pour tous Organic compound - Wikipedia Methane, CH4; it is one of the simplest organic compounds. An organic compound is virtually any chemical compound that contains carbon, although a consensus definition remains elusive and likely arbitrary. Organic compounds are rare terrestrially, but of central importance because all known life is based on organic compounds. The most basic petrochemicals are considered the building blocks of organic chemistry. Definitions of organic vs inorganic For historical reasons discussed below, a few types of carbon-containing compounds, such as carbides, carbonates, simple oxides of carbon (for example, CO and CO2), and cyanides are considered inorganic. The distinction between organic and inorganic carbon compounds, while "useful in organizing the vast subject of chemistry... is somewhat arbitrary". Organic chemistry is the science concerned with all aspects of organic compounds. History Vitalism The word organic is historical, dating to the 1st century. Databases
