Reaction C6H14 structure H (kJ/mol) a. C6H14 + 19/2 O2 —> 6 CO2 + 7 H2O -4,163 b. C6H14 + 19/2 O2 —> 6 CO2 + 7 H2O -4,157These notes represent a detailed interpretation of the professor’s lecture.

Oxidation-Reduction in Organic ChemistryA. Oxidation: adding bonds to oxygen and/or removing hydrogenB. Reduction: removing bonds to oxygen and/or adding hydrogenChapter 3: Alkanes and Cycloalkanes: Conformations and cis-trans Stereoiso-mersI. Conformations of AlkanesA. Eclipsed Conformation: when front and back are in alignmentB. Staggered Conformation: when front and back are not alignedEclipsed and Staggered are the two extremesC. Newman Projections: a form of drawing depicting one bond right be- hind anotherDe- picted below are Newman Projections of the Eclipsed Conformation with the back molecule shown just slightly off of the front molecule: they ARE in line, but this depiction is the best, and most accepted. The second in a Staggered Conformation, which is much more sta-ble than the Eclipsed.D. Torsion Angles1. Eclipsed: 0 degrees-each pair of eclipsing Hydrogens costs 4 kJ/mol2. Gouche: 60 degrees3.
