Organic Chemistry – Hydrocarbons


The study of organic chemistry is the study of the chemistry of carbon compounds. Not all carbon compounds are counted as organic, the rule excludes carbonates (x-CO₃), carbon monoxide (CO) and carbon dioxide (CO₂).
Hydrocarbons contain hydrogen (H) and carbon only. They are divided into groups such as alkanes, alkynes, alkenes and alcohols, and are homologous series. Homologous series are, accodring to, “any of a number of series of organic compounds with similar chemical properties in which members can be described by a general formula and ofen differ by a constant relative molecular mass”.


Alkanes are, thanks to their purely single carbon bonds (C-C), saturated. Physical properties include low melting- and boiling points considering the molar mass. They do not conduct, have low densities and do not solve in water.
