Hydrocarbons2
The structure - reactivity concept is involved in the modern teaching of organic chemistry of the main groups of hydrocarbons and their monofunctional derivatives: alkanes, alkenes, alkynes, arenes, and their halo derivatives, alcohols and phenols, carbonyl compounds, carboxylic acids and functional derivatives of carboxylic acids.

(iso.org)
Nomenclature2
The IUPAC nomenclature (systematic way of naming compounds) for alkanes is based on identifying hydrocarbon chains. (wikipedia.org)
Combining the names of functional groups with the names of the parent alkanes generates what is termed a systematic nomenclature for naming organic compounds . (wikipedia.org)
Cyclic2
Very complicated structures are possible by combining linear, branch, cyclic alkanes. (wikipedia.org)
One of the first consequences of the fact that carbon can form rings can be found by comparing the condensed molecular formulae of linear alkanes with cyclic alkanes. (club1.com.ua)
Homologous series1
With their repeated -CH2 units, the alkanes constitute a homologous series of organic compounds in which the members differ in molecular mass by multiples of 14.03 u (the total mass of each such methylene-bridge unit, which comprises a single carbon atom of mass 12.01 u and two hydrogen atoms of mass ~1.01 u each). (wikipedia.org)
Alkenes1

Two general families of chaperones are reconized: Molecular chaperones, which bind and stabilize un- folded or partly folded proteins, thereby preventing these proteins from aggregating and being degraded Chaperonins, which directly facilitate the folding of proteins Molecular chaperones consist of Tradee and its homologs: Hsp70 in the cytosol and mitochondrial matrix, BiP in the en- doplasmic reticulum, and DnaK in bacteria.

Carbon atoms6
In other words, an alkane consists of hydrogen and carbon atoms arranged in a tree structure in which all the carbon-carbon bonds are single. (wikipedia.org)
In an alkane, each carbon atom is sp3-hybridized with 4 sigma bonds (either C-C or C-H), and each hydrogen atom is joined to one of the carbon atoms (in a C-H bond). (wikipedia.org)
The number of carbon atoms may be considered as the size of the alkane. (wikipedia.org)
Alkanes with more than three carbon atoms can be arranged in various ways, forming structural isomers. (wikipedia.org)
The simplest isomer of an alkane is the one in which the carbon atoms are arranged in a single chain with no branches. (wikipedia.org)
In addition to the alkane isomers, the chain of carbon atoms may form one or more rings. (wikipedia.org)
Molecules2
The alkanes range in complexity from the simplest case of methane (CH4), where n = 1 (sometimes called the parent molecule), to arbitrarily large and complex molecules, like pentacontane (C50H102) or 6-ethyl-2-methyl-5-(1-methylethyl) octane, an isomer of tetradecane (C14H30). (wikipedia.org)
Ethane and pentane are the type of alkane molecules released as a result of lipid peroxidation, symptomatic of oxidative stress in cells. (owlstonemedical.com)
Aldehydes2
Tests were conducted for two aromatics (toluene and ethylbenzene) and two aldehydes (formaldehyde and acetaldehyde) as individual compound and binary mixture, and three alkanes (octane, decane and dodecane) as individual compound, binary and ternary mixtures. (syr.edu)
As for alkanes and aldehydes, the reaction rate was linearly dependent on the reactant concentration within the tested concentration range. (syr.edu)
Reactivity3

In contrast to the 3d transition-metal dimers M2+, which exhibit a relatively low reactivity towards small alkanes, the pronounced reactivity of Ni2+ and nickel-containing dimers NiM+ in general is remarkable, especially when combined with a late 3d transition metal or with aluminum. (tu-berlin.de)
