Aromatski ugljikovodici by Sejma Emina on Prezi

The simplest are compounds such as tetrachloromethane CCl 4tetrabromomethane CBr 4etc. In the systematic chemical nomenclature, alkene names end in the suffix -ene.

Alkenes are acyclic branched or unbranched hydrocarbons having one or more double carbon-carbon bonds in their molecules. The most important of these are: The lower members of the series are gases; aromatsk high-molecular mass alkanes are waxy solid.

Alkenes that have only one double bond form a homologous series: It is lighter than air, easily soluble in acetone propanone and it is explosive under high pressure. Alkanes are present in natural gas and petroleum.

Their carbon chain has one or more double or triple valence bond per molecule. Alkynes acetylenes are acyclic ugljikovoici or unbranched hydrocarbons having one or more triple carbon-carbon bond.

They have C n H 2 n general formula e. The most important of these are:. Halocarbon is a compound containing no elements other than carbon, one or more halogens, and sometimes hydrogen.

In the systematic chemical nomenclature alkyne names end in the suffix -yne.

They form haloalkanes with halogens when irradiated with ultraviolet radiation. Generaly the alkanes are fairly unreactive. Historical use of the term implies a ring containing only carbon e. 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.

Like alkenes, alkynes undergo ugljikovodoci reaction.

All the bonds in benzene C 6 H 6 are the same length intermediate between double and single C-C bonds. Aromatic compounds are unsaturated compounds, yet they do not easily partake in addition reactions. Unsaturated fatty acid is a fatty acid whose carbon chain can absorb additional hydrogen atoms. 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. Alicyclic compounds are aliphatic compounds with a ring of atoms. Alkynes that have only one triple bond form a homologous series: Alkenes typically undergo addition reactions to the double bond.

In the systematic ugljikoodici nomenclature alkane names end in the suffix -ane. Acetylene ethyne is a colourless unstable gas, C 2 H 2with a characteristic sweet odour. The lower members of the various homologous series are used as refrigerants, propellant gases, fireextinguishing agents, and blowing agents for urethane foams.
