	Organic Gases (Volatile Organic Compounds - VOCs) \| An Introduction to Indoor Air Quality \| Indoor Air \| Air \| US EPA
		Some organics can cause cancer in animals; some are suspected or known to cause cancer in humans.
		The ability of organic chemicals to cause health effects varies greatly from those that are highly toxic, to those with no known health effect.
		Many organic compounds are known to cause cancer in animals; some are suspected of causing, or are known to cause, cancer in humans.

	Feldspar Dissolution Kinetics
		Organic compounds in natural waters are thought to interact at the silicate surface and accelerate mineral weathering processes.
		Organic ligands are suggested to chelate and mobilize heavy metals, sorb to mineral surfaces, and enhance the dissolution and the precipitation of inorganic minerals in aqueous systems (e.g., Bennett, 1991).
		Grandstaff (1986) found that some organic acids accelerate olivine dissolution and that the relative reactivity of organic compounds is related to the ability of the organic ligand to form complexes with metals.

		Reaction Mechanisms, including nucleophilic and electrophilic substitution, addition and elimination reactions, free radical reactions, cycloaddition reactions, molecular rearrangements, photochemical reactions, oxidation and reduction reactions, and metal mediated reactions.
		It is recommended that the laboratory material traditionally referred to as "Qualititative Organic Analysis" be incorporated into the second semester of the two-semester laboratory sequence associated with the majors' course in organic chemistry.
		An advanced laboratory course in organic chemistry might then be devoted to modern methods of organic synthesis (e.g., multi-step syntheses) and advanced aspects of chemical separation and identification designed as an introduction to modern methods of organic chemical research.

	Fenton's Reaction
		The mechanism of reaction with respect to hydrogen peroxide is very complex and may change with conditions of the reaction.
		This means that the reaction must be watched more closely as the heat released during the reaction has the potential to raise the temperature too high in a short period of time, causing the liquid to boil.
		The reaction may appear to be continuing at a higher pH, but measuring the changes in peroxide concentration shows that the reaction being observed is actually the acidic peroxide reacting with the more basic solution.

	Naming Organic Reactions - Reaction of Alkanes
		Elimination is an chemical reaction in which a pair of atoms or groups of atoms are removed from a molecule by reacting it with an acid or a base.
		For organic reactions, an alkyl halide reacts with a hydroxide ion to produce an alkene and therefore removing a hydrogen atom and a halide ion from the molecule.
		Condensation is an organic reaction when two molecules combine, usually in the presence of a catalyst, with the elimination of water or some other simple molecule.

	WebReactions Home Page
		A major activity for synthetic chemists is to find literature precedents for a reaction query, either a particular transformation of a specified compound or a more general search for matching analogs at various levels of similarity.
		However, reactions are very complex if described in terms of the full structures of reactant and product, and so only a few thousand entries can be easily searched in a reasonable time.
		WebReactions introduces a new concept for the retrieval of reactions from a large database in which reactions are indexed instead by the bond changes which occur.

	R
		At least in the context of physical organic chemistry, it seems desirable to cease using the adjective "free" in the general name of this type of chemical species and molecular entity, so that the term "free radical" may in future be restricted to those radicals which do not form parts of radical pairs.
		In the formalism of "transition-state theory", the reaction coordinate is that coordinate in a set of curvilinear coordinates obtained from the conventional ones for the reactants which, for each reaction step, leads smoothly from the configuration of the reactants through that of the transition state to the configuration of the products.
		The elementary reaction or reaction stage (of a molecular rearrangement) in which there is both making and breaking of bonds between atoms common to a reactant and a reaction product or a reaction intermediate.

		For a reaction to occur, the reactants must be brought together physically, and in such an orientation that the reaction may proceed, rather than repulsion.
		For a reaction to occur, the reagents must be able to try out various alternatives to see which ones will lead to a reduction in free energy, so that the reaction may proceed.

		The conditions of reaction are typically for carbocation and with migration, one common type of intermediate is the bridged phenomium ion from NGP.
		Using the principles in carbocation reactions, the 1,2-rearrangement in the Bayer-Villiger intermediate will need to break bond to rearrange to an ester product or to give a carbocation at the potential benzene-C after breaking bond-a.
		In the present case it is not a case of stabilization by hypeconjugation or some inductive effect, the twisting motion brings into play the size of the methyl groups.

	Organic Reaction Mechanisms
		Thus Groutas has provided not a thorough treatise on organic reaction mechanisms to compete with Peter Sykes' "A Guidebook to Mechanism in Organic Chemistry", but what is best regarded as a workbook to lead students through the process of deducing organic reaction mechanisms.
		I would prefer there to be greater use of the terms nucleophile and electrophile and more mention of stereochemistry and the shape of molecules, nevertheless it is a valuable source of problems with solutions, space for which in general organic textbooks is usually rather limited.
		This hands-on manual allows readers to gain a better understanding of organic reaction mechanisms by solving a wide range of problems.

		To carry the USDA seal, livestock producers are required to meet strict conditions, including feeding animals 100 percent organic grain or allowing them to graze in ``organically handled'' pasture.
		A provision within the so-called omnibus federal spending package would drop the rule when organic feed costs are more than double that of conventional feed.
		Congress is expected by the end of the week to approve the long-delayed spending bill that will fund almost every area of the U.S. government exceptthe Pentagon.

		equivalent to ozonolysis of the corresponding olefins (reaction 10)
		E1 mechanism for tertiary or secondary allylic or benzylic substrates: the leaving group departs in a unimolecular rate-limiting step, generating the carbocation, which in the second step is deprotonated (with base) on the carbon adjacent to the cationc center, yielding the olefin; carbocation rearrangements may compete
		E2 mechanism favored by strong bases: the base removes a proton from the carbon adjacent to one bearing the leaving group in a one-step bimolecular reaction that requires periplanar orientation of the hydrogen and the leaving group (anti-periplanar preferred)

	JCE Online: JCE WebWare: Web-Based Interactive Animation of Organic Reactions
		One of the major obstacles in learning organic chemistry is the need for a three-dimensional perspective of the molecules and the reaction pathways that they follow.
		To overcome the current limitations of viewing organic reactions, we have developed a Web-based, interactive procedure that allows for the animation of an organic reaction, presented as an interactively viewable Chime object (2), on the basis of an approximate structure of the corresponding transition state.
		It can be used by teachers to demonstrate and explain the three-dimensional course of organic reactions and it is useful for students to design and investigate their own reaction examples.

	Reasonable Mechanisms Textbook
		The general approach of the book is to classify reactions according to their mechanisms and the reaction conditions under which they proceed, not according to the transformations they achieve.
		Reactions which are not used widely or have been largely supplanted are generally not discussed, and newer reactions and reagents are often mentioned.
		A working knowledge of the mechanisms of these reactions is indispensable to the practicing organic chemist, yet they are usually not discussed in organic chemistry textbooks or classes.
