Unit 2 Application of Core Principles of Chemistry - 2.12 - Mass spectra and IR
Students will be assessed on their ability to:
a) interpret fragment ion peaks in the mass spectra of simple organic compounds, eg the difference between propanal and propanone
b) use infrared spectra, or data from infrared spectra, to deduce functional groups present in organic compounds and predict infrared absorptions, given wavenumber data, due to familiar functional groups. This will be limited to:
c) demonstrate an understanding that only molecules which change their polarity as they vibrate can absorb infrared radiation
d) demonstrate an understanding that H2O, CO2, CH4 and NO molecules absorb IR radiation and are greenhouse gases, whilst O2 and N2 are not.
