| Question | Answer |
|---|---|
| Protic solvent | solvent that provides a source of protons (H+) eg. water, ethanol |
| Aprotic solvent | solvent that does not provide a source of protons (H+)eg. propanone, hexane |
| Markovnikov's rule | the hydrogen will attach to the carbon that is already bonded to the greater number of hydrogens |
| Cis isomers | Isomers with the same groups on the same side of the double bond or cyclical compounds |
| Trans isomers | Isomers that have the groups on the opposite sides of the double bond |
| Chiral carbon | Carbon that have 4 different groups |
| Enantiomers | Optical isomers that exist in pairs |
| Diastereomers | Optical isomers that contain two or more chiral carbons that are not mirror images of each other |
| Condensation reactions | The production of a small molecule eg. H2O, NH3, or HCl when two functional groups join |
| Polyester | condensation polymer of alcohol and carboxylic acid (ester link) |
| Polyamide | condensation polymer of amine and carboxylic acid (amide link) |
| Hydrolysis | Addition of water to break a chemical bond |
| Stereoisomers | Same molecular formula and same structural formula |
| Conformational isomer | Stereoisomer due to rotation around a bond |
| Configurational isomer | Stereoisomer that is not due to rotation around a bond and requires breaking of a bond to form |
| Optical isomer | Contains a chiral carbon with 4 different groups attached |
| Geometrical isomers | Configurational isomers around a double bond |
| Racemate mixture | or Racemic mixture - contains 50-50 mixture of 2 enantiomers |
| H NMR | Proton nuclear magnetic resonance spectroscopy |
| Wavenumber and wavelength conversion formula | wavernumber = 1/wavelength |
| Chemical shift | ppm increase in resonating compared to TMS standard |
| Integration trace | Area under the curve indicating number of hydrogens in the molecule and per environment |
