WHAT'S THIS STANDARD ABOUT??

WHY WOULD WE NEED TO KNOW THIS??
Let's say.....
- You're prosecuting a drunk driver and need an accurate blood alcohol reading
- You're investigating a possible art forgery and want to know if you've got the real painting or not
- You want to test the exact amount of certain components of a food item you are manufacturing
- You are investigating the possible presence of environmental toxins
- You work for WADA and are investigating allegations of steroid use in athletes
- You work for the government and need to be able to detect biological or chemical weapons
- You are a research scientist and are developing drugs for combating disease and you want to make sure you have synthesised the correct molecule
THIS STANDARD CONSISTS OF:
For Achieved you must identify aspects of the structure of organic molecules using teacher provided spectroscopic data.
For Merit you must determine the structure of organic molecules using spectroscopic data.
For Excellence you must justify the structure of organic molecules by integrating spectroscopic data.
Spectroscopic data is limited to that collected from mass, infrared (IR) and 13C nuclear magnetic resonance (NMR) spectroscopy.
Organic molecules are limited to alkanes, alkenes, alcohols, haloalkanes, amines, aldehydes, ketones, carboxylic acids, amides, acid chlorides and esters.
Aspects of structure are limited to molar mass and molecular formulae, functional groups, and the carbon framework including structural isomers.

Briefly:
1. Use the MASS SPECTRA to determine the MOLECULAR MASS and the mass of FRAGMENTS of the MOLECULE
2. Use 13C NMR SPECTRA to determine the NUMBER OF UNIQUE CARBON ENVIRONMENTS (related to symmetry) (and also some information about functional groups)
3. Use the IR SPECTRA to determine the presence and absence of FUNCTIONAL GROUPS
Put them all together to DETERMINE and JUSTIFY the CORRECT STRUCTURE!
