Self Assessment Checklist
Alkanes | I can do this! | |
(a) | Describe an homologous series as a group of compounds with a general formula, similar chemical properties and showing a gradation in physical properties as a result of increase in the size and mass of the molecules, e.g. melting and boiling points; viscosity; flammability. | |
(b) | Describe the alkanes as an homologous series of saturated hydrocarbons with the general formula CnH2n+2. | |
(c) | Draw the structures of branched and unbranched alkanes, C1 to C4, and name the unbranched alkanes methane to butane. | |
(d) | Define isomerism and identify isomers. | |
(e) | Describe the properties of alkanes (exemplified by methane) as being generally unreactive except in terms of combustion and substitution by chlorine. |
