Learning Objectives

Students should:
$be able to use data from infrared spectra to deduce functional groups present in organic compounds and to predict infrared absorptions, given wavenumber data, due to familiar functional groups, including: i C-H stretching absorption in alkanes, alkenes and aldehydes ii C=C stretching absorption in alkenes iii O-H stretching absorption in alcohols iv C=O stretching absorption in aldehydes and ketones v C=O stretching absorption and the broad O-H stretching absorption in carboxylic acids vi N-H stretching absorption in amines$
$CORE PRACTICAL 7: Analysis of some inorganic and organic unknowns$
