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.

When polymerized, they yield plastics characterized by extreme chemical resistance, high electrical resistivity, and good heat resistance. Historical use of the term implies a ring containing only carbon e. Alkenes are acyclic branched or unbranched hydrocarbons having one or more double carbon-carbon bonds in their molecules. The most important of these are: Like alkenes, ugljijovodici undergo addition reaction.

Alkanes are present in natural gas and petroleum. In the systematic chemical nomenclature, alkene names end in the suffix -ene. Aromatic compounds are unsaturated compounds, yet they do not easily partake in addition reactions.


Unsaturated hydrocarbons are aromatwki compounds containing double alkenes or triple alkynes bonds in their molecules. Alkenes that have only one double bond form a homologous series: Halocarbon is a compound containing no elements other than carbon, one or more halogens, and sometimes hydrogen. The simplest are compounds such as tetrachloromethane CCl 4tetrabromomethane CBr 4etc.

Category:Aromatic hydrocarbons

They form haloalkanes with halogens when irradiated with ultraviolet radiation. The lower members of the series are gases; the high-molecular mass alkanes are waxy solid. 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. It is lighter than air, easily soluble in acetone propanone and it is explosive under high pressure. Generaly the alkanes are fairly unreactive.

They have C n H ugljikofodici n general formula e.

Alkynes acetylenes are acyclic branched or unbranched hydrocarbons having one or more triple carbon-carbon bond. Their carbon chain has one or more ugljikovodivi or triple valence bond per molecule. Unsaturated fatty acid is a fatty acid ugljiovodici carbon chain can absorb additional hydrogen atoms. Alkynes that have only one triple bond form a homologous series: The most important of these are:. In the systematic chemical nomenclature alkane names end in the suffix -ane. All the bonds in benzene C 6 H 6 are the same length intermediate between double and single C-C bonds.


Alicyclic compounds are aliphatic compounds with a ring of atoms. Alkenes typically undergo addition reactions to the double bond. In the systematic chemical nomenclature alkyne names end in the suffix -yne.
