11.2 Alkanes

O Level - Pure Chemistry

(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 burning and substitution by chlorine

O Level - Combined Chemistry

(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 unbranched alkanes, C1 to C3 and name the unbranched alkanes, methane to propane
(d) describe the properties of alkanes (exemplified by methane) as being generally unreactive except in terms of burning and substitution by chlorine

N(A) Level - Combined Chemistry

(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
