Related termsFrom Wiktionary under the GNU Free Documentation License. In chemistry, an alkyl group is an alkane missing one hydrogen. It has the general formula CnH2n+1. Typically an alkyl is a part of a larger molecule. In structural formulae, the symbol R is used to designate a generic (unspecified) alkyl group. The smallest alkyl group is methyl, with the formula CH3—. Alkyls in everyday lifeThe word root alkyl is encountered in several contexts in everyday life. Alkylation is an important operation in refineries, for example in the production of high-octane gasoline. Alkylating antineoplastic agents refer to a class of compounds that are used to treat cancer. In such case, the term alkyl is used loosely. For example, nitrogen mustards are well-known alkylating agents, but they are more complex than a mere hydrocarbon. In chemistry, alkyl refers to a group, a substituent, that is attached to other molecular fragments. For example, alkyl lithium reagents have the empirical formula Li(alkyl), where alkyl = methyl, ethyl, etc. A dialkyl ether is an ether with two alkyl groups, e.g., diethyl ether (O(C2H5)2).

GNU Free Documentation License What is the difference between alkyl chemistry and aromatic chemistry? Q. I have an idea but I just don't know how to put it in to words Asked by Katie - Tue Jul 28 20:42:31 2009 - - 3 Answers - 0 Comments A. "Alkyl chemistry" is a matter of straight- and branched-chain hydrocarbons. The reactions occur via carbonium ion, carbanion, carbene, and free radical reactive intermediates. "Aromatic chemistry" is mostly a matter of the benzene ring and related compounds like naphthalene, anthracene, and pyridine. In electrophilic aromatic substitution, electrophiles like X+ attack benzene and the benzene ring restores itself with the production of C6H5-X + H+. In nucleophilic aromatic substitution, nucleophiles like NH2- attack pyridine to form a mix of 2- and 4-aminopyridines.

Asked by adamaltmann - Mon Jan 8 09:27:50 2007 - - 1 Answers - 0 Comments A. Lancenigo di Villorba (TV), Italy Benzene is the substrate and former reactant both. Benzene can be solvent of the second reactive, alkyl halide, so you obtain benzenic solution of the halo-compound. In beginning of XX century, two scientists (the french chemist Friedel and the american's one Crafts) overcoming to discovery of this reaction : adding traces of aluminium chloride or other strong Lewis's acids to benzenic solution of methyl chloride leads to taking place of a reaction, the latter produces toluene. It belong to classes of reaction named like "Electrophilic Aromatic Substitution", more precisely "Electrophilic Alkylation" of aromatic compounds. Aromatic substrate is benzene itself, the most common (not the simplest, e.g. furan) [cont.] Answered by Zor Prime - Mon Jan 8 10:37:45 2007 What is the chemical formula for n-Alkyl Dimethyl Benzyl Ammonium Chloride?
