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.

Aromatic compounds are unsaturated compounds, yet they do not easily partake in addition reactions. Alkynes that have only one triple bond form a homologous series: Alkenes that ugljikogodici only one double bond form a homologous series: Historical use of the term implies a ring containing only carbon e.

In the systematic chemical nomenclature alkane names end in the suffix -ane. The simplest are compounds such as tetrachloromethane CCl 4tetrabromomethane CBr 4etc. Alkanes are present in natural gas and petroleum.
Like alkenes, alkynes undergo addition reaction. They form haloalkanes with halogens when irradiated with ultraviolet radiation. In the systematic chemical nomenclature, alkene names end in the suffix -ene. All the bonds in benzene C 6 H 6 are the same length intermediate between double and single C-C 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. Image Gallery Analytical chemistry Crystal systems Electrodes and cells Graphs and tables Hazard labels Laboratory apparatus Laboratory glassware Molecular geometry Structural formulas.
Their carbon chain has one or more double or triple valence bond per molecule. The lower members of the various homologous series are used as refrigerants, propellant gases, fireextinguishing agents, and blowing agents for urethane foams. Alkenes typically undergo addition reactions adomatski the double bond. Alicyclic compounds are aliphatic compounds with a ring of atoms. Acetylene ethyne is a colourless unstable gas, C 2 H 2with a characteristic uglhikovodici odour.
Halocarbon is a compound containing no elements other than carbon, one or more halogens, and sometimes hydrogen.

They have C n H 2 n general formula e. Alkynes acetylenes are acyclic branched or unbranched hydrocarbons having one or more triple carbon-carbon bond. In the systematic chemical nomenclature alkyne names end in the suffix -yne. Generaly the alkanes are fairly unreactive. Aromatic compounds are a major group of unsaturated cyclic hydrocarbons containing one or more rings, ugljikovoddici by benzene, which has a 6-carbon ring containing three double bonds.
Unsaturated hydrocarbons are organic compounds containing double alkenes or triple alkynes bonds in their molecules. When polymerized, they yield plastics characterized by extreme chemical resistance, high electrical resistivity, and good heat resistance.
The most important of these are:. The most important of these are: Alkenes are acyclic branched or unbranched hydrocarbons having one or more double carbon-carbon bonds in their molecules.
Unsaturated fatty acid is a fatty ugljikovodico whose carbon chain can absorb additional hydrogen atoms.
