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.

When polymerized, they yield plastics characterized by extreme chemical resistance, high electrical resistivity, and good heat resistance. Unsaturated hydrocarbons are organic compounds containing double alkenes or triple alkynes bonds in their molecules. All the bonds in benzene C 6 H 6 are the same length intermediate between double and single C-C bonds.
Historical use of the term implies a ring containing only carbon e.
They have C n H 2 n general formula e. Alkenes are acyclic branched or unbranched hydrocarbons having one or more double carbon-carbon bonds in their molecules.

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. Generaly the alkanes are fairly unreactive.
Alkynes acetylenes are acyclic branched or unbranched hydrocarbons having one or more triple carbon-carbon bond. Alkynes that have only one triple bond form a homologous series: The simplest are compounds such as tetrachloromethane CCl 4tetrabromomethane CBr 4etc.
The lower members of the series are gases; the high-molecular mass alkanes are waxy solid. In the systematic chemical nomenclature, alkene names end in the suffix -ene. The most important of these are:. In the systematic chemical nomenclature alkane names end in the suffix -ane. In the systematic chemical nomenclature alkyne names end in the suffix -yne. Unsaturated fatty acid is a fatty acid whose carbon chain can absorb additional hydrogen atoms.
Like alkenes, alkynes undergo addition reaction. Alkenes that have only one double bond form a homologous series: They form haloalkanes with halogens when ugljjkovodici with ultraviolet radiation.

Halocarbon is a compound containing no elements other than carbon, one or more halogens, and sometimes hydrogen. Their carbon chain has one or more double or triple valence bond per molecule.
Alkenes typically undergo addition reactions to the double bond.
The lower members of the various homologous series are used as refrigerants, propellant gases, fireextinguishing agents, and blowing agents for urethane foams.
Aromatic compounds are unsaturated compounds, yet they do not easily partake in addition reactions.
Alicyclic compounds are aliphatic compounds with a ring of atoms. 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 odour.
