Alkanes And Its IUPAC Names
Alkanes are the hydrocarbons containing Carbon and Hydrogen attached by a single bond. Alkanes are known as paraffins (Parum =less, affinity = reactivity). General formula of Alkane is C n H 2n+2 IF n = 1 then C 1 H 2x1+2 = CH 4 Methane IF n = 2 then C 2 H 2x2+2 = C 2 H 6 Ethane IF n = 3 then C 2 H 2x2+2 = C 3 H 8 Propane and so on..... IUPAC names of first 20 straight chain alkanes are as follows, Number of C atoms Molecular Formula Name of straight chain Structural Formula 1 CH 4 methane CH 4 2 C 2 H 6 ethane CH 3 -CH 3 3 C 3 H 8 propane CH 3 -CH 2 -CH 3 4 C 4 H 10 n-butane CH 3 -CH 2 -CH 2 -CH 3 5 C 5 H 12 n-pentane CH 3 CH 2 CH 2 CH 2 CH 3 6 C 6 H 14 n-hexane CH 3 CH 2 CH 2 CH 2 ...
