Infrared spectroscopy: functional groups Keywords: infrared, radiation, absorption, spectroscopy

Identify, using C=O and O–H absorptions, an alcohol, an aldehyde or ketone and a carboxylic acid. Learning objective

The information generated from an infrared spectrum can be used to identify the functional groups in a molecule using a reference data sheet. You will need to identify the presence of these functional groups: AlcoholsHydroxylO-H Aldehydes + ketonesCarbonylC=O Carboxylic acidCarboxylC-O C=O O-H Organic compoundsC-H~3000

Alcohols

Aldehydes and ketones

Carboxylic acids

Task:

StretchO-HC-HC=OC-O A lcohols C arbonyls C arboxylics

Stretch O-H C-H C=O C-O A lcohols C arbonyls C arboxylics Very Broad
