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.

Like alkenes, alkynes undergo addition reaction. The most important of these are: Alkynes that have only one triple bond form a homologous series: All the bonds in benzene C 6 H 6 are the same length intermediate between double and single C-C bonds.

Generaly the alkanes are fairly unreactive. In the systematic chemical nomenclature alkane names end in the suffix -ane.


They form haloalkanes with halogens when irradiated with ugljiklvodici 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.


The most important of these are:. The lower members of the series are gases; the high-molecular mass alkanes are waxy solid.

They have C n H 2 n general formula e.

Alkenes typically undergo addition reactions to the double bond. Aromatic compounds are unsaturated compounds, yet they do not easily partake in addition raomatski. Historical use of the term implies a ring containing only carbon e. Alkanes are present in natural gas and petroleum. When polymerized, they yield plastics characterized by extreme chemical resistance, high electrical resistivity, and good heat resistance.

Alkenes that have only one double bond form a homologous series: Aromatic compounds are a ugljikovodcii group of unsaturated cyclic hydrocarbons containing one or more rings, typified by benzene, which has a 6-carbon ring containing three double bonds. The simplest are compounds such as tetrachloromethane CCl 4tetrabromomethane CBr 4etc. Alkenes are acyclic branched or unbranched hydrocarbons having one or more double carbon-carbon bonds in their molecules.


Acetylene ethyne is a colourless unstable gas, C 2 H 2with a characteristic sweet odour. In the systematic chemical nomenclature, alkene names end in the suffix -ene. In the systematic chemical nomenclature alkyne names end in the suffix -yne. Alicyclic compounds are aliphatic compounds with a ring of atoms.

Aromatski ugljikovodici

It is lighter than air, easily soluble in acetone propanone and it is explosive under high pressure. Unsaturated hydrocarbons are organic compounds containing double alkenes or triple alkynes bonds in their molecules. Alkynes acetylenes are acyclic branched or unbranched ugljikivodici having one or more triple carbon-carbon bond. The lower members of the various homologous series are used as refrigerants, propellant gases, fireextinguishing agents, and blowing agents for urethane foams.
