If the branches (substituted groups) are smaller chain hydrocarbons theyare called alkyl groups.An alkyl group is a group derived by removing a single hydrogen atom from an alkanemolecule, thus creating a point of attachment. The letter “R” is used as a general symbolfor alkyl groups.AlkaneAlkyl -Rmethane(CH 4 ) methyl-CH 3ethane(CH 3 CH 3 )ethyl-CH 2 CH 3propane(CH 3 CH 2 CH 3 )propyl-CH 2 CH 2 CH 3isopropylCH 3 CHCH 37-6
