Nomenclature and Isomers Familiarize yourself with the functional groups listed on page 70-71 in McMurry. Constitutional Isomers -same number of each type of atom with different conformation. These isomers often have different properties as shown in the molecules below. OH OH C 3 H 8 O Mol. Wt.: 60.10 C 3 H 8 O Mol. Wt.: 60.10 M.P. = -88.5 °C B.P. = 82.4 °C Propan-2-ol Propan-1-ol M.P. = -126 °C B.P. = 97.2 °C M.P. = -138.5 °C B.P. = -22 °C M.P. = -114.1 °C B.P. = 78.3 °C O OH dimethyl ether ethanol C 2 H 6 O Mol. Wt.: 46.07 C 2 H 6 O Mol. Wt.: 46.07 Alkanes : Fully saturated hydrocarbon. End in –ane root. Examples: Methane, Ethane, Propane, Butane, Pentane, Hexane, Heptane, Octane, Nonane, Decane… Cycloalkanes : Have carbon ring structures, one degree of unsaturation. Examples: Cyclopropane, Cyclobutane, Cyclopenate, Cyclohexane, Cycloheptane, Cyclooctane, Cyclononane, Cyclododecane… Alkyl Group : Alkanes or cycloalkanes substituted at one hydrogen.
