Encyclopedia > Alkyl cycloalkane

Alkyl cycloalkanes are chemical compounds with an alkyl group with a single ring of carbons to which hydrogens are attached according to the formula A chemical compound is a chemical substance formed from two or more elements, with a fixed ratio determining the composition. ... An alkyl is a functional group of an organic chemical that contains only carbon and hydrogen atoms, which are arranged in a chain. ... General Name, Symbol, Number Carbon, C, 6 Chemical series Nonmetals Group, Period, Block 14 (IVA), 2, p Density, Hardness 2267 kg/m3 0. ... General Name, Symbol, Number Hydrogen, H, 1 Chemical series nonmetals Group, Period, Block 1 (IA), 1, s Density, Hardness 0. ...

CnH2n.

They are named analogously to their normal alkane counterpart of the same carbon count: methylcyclopropane, methylcyclobutane, methylcyclopentane, methylcyclohexane, etc. An alkane in organic chemistry is a saturated hydrocarbon, that is, a hydrocarbon in which the molecule has the maximum possible number of hydrogen atoms and so has no double bonds. ... Methylcyclopropane is the alkyl cycloalkane compound of methane and cyclopropane. ...


Methylcycloalkanes are classed into compounds with small, normal and bigger cycloalcanes, where cyclopropane and cyclopbutane are the small ones, cyclopentane, cyclohexane, cycloheptane are the normal ones and the rest are the bigger ones.

Nomenclature

The naming of polycyclic alkanes is more complex, with the base name indicating the number of carbons in the ring system, a prefix indicating the number of rings (eg, "bicyclo"), and a numeric prefix before that indicating the number of carbons in each part of each ring, exclusive of vertices. For instance, a bicyclooctane which consists of a six-member ring and a four member ring, which share two adjacent carbon atoms which form a shared edge, is [4.2.0]-bicyclooctane. That part of the six-member ring, exclusive of the shared edge has 4 carbons. That part of the four-member ring, exclusive of the shared edge, has 2 carbons. The edge itself, exclusive of the two vertices that define it, has 0 carbons.


Reactions

The normal and the bigger alkylcycloalkanes are very stable like alkanes and their reactions (cf. radicalic chain reactions) are like alkanes. An alkane in organic chemistry is a type of hydrocarbon in which the molecule has the maximum possible number of hydrogen atoms and so has no double bonds (they are saturated). ...


The small alkylcycloalkanes - particulary alkylcycloprapane - has a lower stability due to the Baeyer-tension. They react similar to alkenes, though they dont react with the EA (cf. electrophilic addition), but with the SN2 (cf. nucleophilic substitution) reaction mechanism. These reactions are both ring opening reactions and cleavage reactions. An alkene is one of the three classes of unsaturated hydrocarbons that contain at least one carbon-carbon double bond and have the general molecular formula of CnH2n (the other two being alkynes and arenes). ... Most addition reactions to alkenes follow the mechanism of electrophilic addition. ... In chemistry, nucleophilic substitution is a type of chemical reaction in which one nucleophile electron donor replaces another as a covalent substitute of some atom. ... Look up cleave or cleavage in Wiktionary, the free dictionary Cleavage has several common meanings, all related to the formation of a line between two parts: Cleavage - partial exposure of the separation between a womans breasts. ...


Typical compound

The typical compound of the group alkyl cycloalkanes is methylcyclopropane. Methylcyclopropane is the alkyl cycloalkane compound of methane and cyclopropane. ...

Cycloalkane - Wikipedia, the free encyclopedia (314 words)
Cycloalkanes are chemical compounds with a one or more rings of carbons to which hydrogens are attached according to the formula C
Cycloalkanes with a single ring are named analogously to their normal alkane counterpart of the same carbon count: cyclopropane, cyclobutane, cyclopentane, cyclohexane, etc. The larger cycloalkanes, with greater than 20 carbon atoms are typically called cycloparaffins.
Cycloalkanes are classified into small, normal and bigger cycloalkanes, where cyclopropane and cyclobutane are the small ones, cyclopentane, cyclohexane, cycloheptane are the normal ones, and the rest are the bigger ones.
Patent 5021492: Rubber compositions containing a mixture of alkyl esters of rosin acid (3294 words)
The process of claim 2 wherein said alkyl ester of rosin acid is added to a rubber selected from the group consisting of natural rubber, homopolymers of conjugated diolefins and copolymers of conjugated diolefins and ethylenically unsaturated monomers.
The mixture of alkyl esters of rosin acid may be used in a wide variety of proportions in the rubber and may be a substitute, in whole or part for conventional waxes.
The vulcanization of the rubber containing the mixture of alkyl (C.sub.6 -C.sub.18) ester of rosin acid is conducted in the presence of a sulfur vulcanizing agent.
