Razvijena je i validirana HPLC metoda za određivanje policikličkih aromatskih ugljikovodika (PAH) u jestivom ulju izoliranih na DACC (eng. donor-acceptor. Kad se aromatski ugljikovodici zagrijavaju s klorom (ili bromom) u prisutnosti željeza, dolazi do supstitucije vodika na jezgri, uz razvijanje halogenovodične. aromatski ugljikovodici translation in Bosnian-Kannada dictionary.

Alkenes are acyclic branched or unbranched hydrocarbons having one or more double carbon-carbon bonds in their molecules. They form haloalkanes with halogens when irradiated with ultraviolet radiation.
The most important of these are: Alkanes are present in natural gas and petroleum. Image Gallery Analytical chemistry Crystal systems Electrodes and cells Graphs and tables Hazard labels Laboratory apparatus Laboratory glassware Molecular geometry Structural formulas. All the bonds in benzene C 6 H 6 are the same length intermediate between double and single C-C bonds. In the systematic chemical nomenclature, alkene names end in the suffix -ene.
When polymerized, they yield plastics characterized by extreme chemical resistance, high electrical resistivity, and good heat resistance.

Alicyclic compounds are aliphatic compounds with a ring of atoms. Unsaturated hydrocarbons are organic compounds containing double alkenes or triple alkynes bonds in their molecules. Like alkenes, alkynes undergo addition reaction. The simplest are compounds such as tetrachloromethane CCl 4tetrabromomethane CBr 4etc.
In the systematic chemical nomenclature alkyne names end in the suffix -yne. Alkenes typically undergo addition reactions to the double bond. In the systematic chemical nomenclature alkane names end in the suffix -ane.
Aromatic compounds are unsaturated compounds, yet aromahski do not easily partake in addition reactions. Alkenes that have only one double bond form a homologous series: They have C n H 2 n general formula e.
The lower members of the various homologous series are used as refrigerants, propellant gases, fireextinguishing agents, and blowing agents for urethane foams. Halocarbon is a compound containing no elements other than carbon, one or more halogens, and sometimes hydrogen.
Historical use of the term implies a ring containing only carbon e. Alkynes acetylenes are acyclic branched or unbranched hydrocarbons having one or more triple carbon-carbon bond.
The most important of these are:. Unsaturated fatty acid is a fatty acid whose carbon chain can absorb additional hydrogen atoms. Alkynes that have only one triple bond form a homologous series: Their carbon chain has one or more double or triple valence bond per molecule. Aromatic compounds are a major group of unsaturated cyclic hydrocarbons containing one or more rings, typified by benzene, which has a 6-carbon ring containing three double bonds.
The lower members of the series are gases; the high-molecular mass alkanes are waxy solid.
It is lighter than air, easily soluble in acetone propanone and it is explosive under high pressure. Acetylene ethyne is a colourless unstable gas, C 2 H 2with a characteristic sweet uglmikovodici. Generaly the alkanes are fairly unreactive.
