|Chapter 2 : Alkanes|
|Functional group suffix =
Functional group prefix = alkyl-
e.g. CH3CH2- = ethyl
More details on alkane nomenclature?
The low polarity of all the bonds in alkanes means that the only intermolecular forces between molecules of alkanes are the very weak induced dipole - induced dipole forces. These forces are easily overcome. As a result, in comparison with other functional groups, alkanes tend to have low melting and boiling points and very low solubility in polar solvents such as water (remember "oil and water don't mix" and the adage "like dissolves like").
Consist of only sp3 hybridised C and H atoms connected by σ bonds.
