analytic techniques Flashcards
1
Q
in infrared spectroscopy whats the difference between C=O, O-H in alcohols, O-H in carboxylic acids
A
C=O has lower wavenumber
O-H in alcohols is more rounded, just above 3000
O-H in carboxylic acids is more jiggered, at 3000
2
Q
what are the uses of IR spectroscopy
A
determine level of pollutants in city, breath tests to detect presence of alcohol
3
Q
what do the peaks in mass spectrometry show
A
largest peal= molecular ion (+), whole compound
peaks of lower mass show how a compound has been fragmented
