Mechanisms
- interpret fragment ion peaks in the mass
spectra of simple organic compounds, eg the
difference between propanal and propanone
- deduce functional groups present in
organic compounds and predict infrared
absorptions, given wavenumber data, due
to familiar functional groups.
- i C–H stretching absorptions in
alkanes, alkenes and aldehydes
ii O–H stretching absorption in
alcohols and carboxylic acids iii
N–H stretching absorption in
amines iv C=O stretching
absorption in aldehydes and
ketones v C–X stretching
absorption in halogenoalkanes vi
as an analytical tool to show the
change in functional groups
during the oxidation of an alcohol
to a carbonyl

- understanding that only molecules
which change their polarity as they
vibrate can absorb infrared
radiation
- understanding that H2O, CO2, CH4 and NO
molecules absorb IR radiation and are greenhouse
gases, whilst O2 and N2 are not.
