Sec 1 Alkanes and Alkane Isomers Alkanes often described as saturated hydrocarbons Hydrocarbons Contain only carbon and hydrogen Saturated Contain maximum possible number of hydrogens per carbon and have only C-C and C-H single bonds Alkanes occasionally referred to as aliphatic compounds,a name derived from the Greek word aleiphas,meaning "fat" Fatty acyl Glycerol Stearoyl (stearic acid) CH2OCCH2CH2CH2CH2CH2CH2CH2CH2CH2CH2CH2CH2CH2CH2CH2CH2CH3 Oleoyl (oleic acid) CHOCCH2CH2CH2CH2CH2CH2CH2CH-CHCH2CH2CH2CH2CH2CH2CH2CH3 Linoleoyl (linoleic acid) CH2OCCH2CH2CH2CH2CH2CH2CH2CH=CHCH2CH-CHCH2CH2CH2CH2CH3 A triacylglycerol Cengnge Leaming All Righes Reporved
