The IUPAC name of isobutane and isopentane has to be determined. Concept Introduction: Alkanes : Saturated hydrocarbons are called as alkanes. Each atom in an alkane shows the presence of four single bonds in a tetrahedral arrangement with sp 3 hybridization. The name of alkane ends with “-ane” . Rules for naming compound: 1) The carbon atoms in the longest chain have to be counted. 2) The substituents have to be identified and counted. 3) The backbone carbon atoms have to be numbered by assigning the lowest number from the starting end.
