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.

In the systematic chemical nomenclature alkane names end in the suffix -ane.

Unsaturated fatty acid is a fatty acid whose carbon chain can absorb additional hydrogen atoms. In the systematic chemical nomenclature, alkene names end in the suffix -ene. Alicyclic compounds are aliphatic compounds with a ring of atoms.

Generaly the alkanes are fairly unreactive. Alkenes are acyclic branched or unbranched hydrocarbons having one or more double carbon-carbon bonds in their molecules. Like alkenes, alkynes undergo addition reaction. 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.

Alkanes are present in natural gas and petroleum. When polymerized, they yield uglmikovodici characterized by extreme chemical resistance, high electrical resistivity, and good heat resistance. They form haloalkanes with halogens when irradiated with ultraviolet radiation. Alkynes that have only one triple bond form a homologous series: Halocarbon is a compound containing no elements other than carbon, one or more halogens, and sometimes hydrogen.

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 alkyne names end in the ugljjkovodici -yne. Alkynes acetylenes are acyclic branched or unbranched hydrocarbons having one or more triple carbon-carbon bond. It is lighter than air, easily soluble in acetone propanone ugljikovodixi it is explosive under high pressure. Alkenes typically undergo addition reactions to the double bond. 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.

Acetylene ethyne is a colourless unstable gas, C 2 H 2with a characteristic sweet odour.

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. Historical use of the term implies a ring containing only carbon e.


The most important of these are:. Aromatic compounds are unsaturated compounds, yet they do not easily partake in addition reactions.

Aromatski ugljikovodici in Kannada – Bosnian-Kannada Dictionary

Alkenes that have only one double bond form a homologous series: The simplest are compounds such as tetrachloromethane CCl 4tetrabromomethane CBr 4etc. Unsaturated hydrocarbons are organic compounds containing double alkenes or triple alkynes bonds in their molecules.

The most important of these are:
