homologous series

Vavilov also formulated the law of homologous series in variation.

"Nor" compares two related compounds; it does not describe the relation to a homologous series.

Homologous series are not unique to organic chemistry.

Such a series is called the homologous series, while its members are called homologs.

Compounds within a homologous series typically have a fixed set of functional groups that gives them similar chemical and physical properties.

Joback assumed a constant contribution of added groups in homologous series like the alkanes.

Boiling points: The boiling points graduate in the same way as other homologous series.

A Homologation reaction is any chemical process which converts one member of a homologous series to the next member.

The difference in the structure of each successive member of a homologous series is CH2-.

Hydrocarbons are grouped into "families" or "homologous series".

Triethylene glycol is a member of a homologous series of dihydroxy alcohols.

As a rule of thumb, the boiling point rises 20-30 C for each carbon added to the chain; this rule applies to other homologous series.

The aliphatic hydrocarbons are subdivided into three groups of homologous series according to their state of saturation:

A homologation reaction, also known as homologization, is any chemical reaction that converts the reactant into the next member of the homologous series.

A Homologous series is a group of compounds that differ by a constant unit, generally a (-CH-) group.

Hydrogen polyoxides belong to a homologous series of inorganic compounds in which the members differ by a constant relative molecular mass of 16.

The possible products include silane and/or higher molecules in the homologous series, a polymeric silicon hydride, or a silicic acid.

Examining organic compounds, the relative intensity of the molecular ion peak diminishes with branching and with increasing mass in a homologous series.

(In contrast, the prefix "homo-" which indicates the next higher member in a homologous series,is usually limited to noncyclic carbons).

Chemists, like physicians, are faced with learning long lists of things, in our case trivial (that is, not systematic) nomenclature for various homologous series of chemical compounds.

In the Arndt-Eistert reaction, a methylene unit is inserted into the carboxyl-carbon bond of carboxylic acid to form the next acid in the homologous series.

Although many natural waxes contain esters, paraffin waxes are hydrocarbons, mixtures of alkanes usually in a homologous series of chain lengths.

The classification of organic compounds into homologous series was advanced as one consequence of his researches into the acids generated by the oxidation of the alcohols.

In chemistry, a homologous series is a series of compounds with a similar general formula, usually varying by a single parameter such as the length of a carbon chain.

Early attempts generally consisted of examining the degradation of a homologous series of structurally related compounds under identical conditions with a complex "universal" inoculum, typically derived from numerous sources.
