Alkanes and the alkane homologous series physical properties of alkanes from the table of the straight chained alkanes it can be seen that there is a gradual change in the physical although this topic is not required at gcse level it is thought a brief introduction would be useful in order to explain. An overview of the chemistry and structure of alkanes all hydrocarbons are the same in that they contain hydrogen and carbon atoms, but they differ in the number of carbons they have, the level of their saturation, whether they are linear or cyclic, and whether they are aromatic or not.
Today we looked at some of the physical and chemical properties of alkanes honestly, this is not very exciting, but it is useful to know these properties and reactions for the latter part of this unit. Alkanes are also known as saturated hydrocarbons and sometimes as paraffins alkanes are a relatively simple group of hydrocarbons and are usually included in introductory courses in organic chemistry school-level chemistry page, ages 14-16, uk gcse or international equivalent.
