Analytical techniques Flashcards
What will test tube reactions be used to do
identify the functional group in an organic compound and therefore, the type of organic compound
What is the test for C=C in alkenes
decolourisation of bromine water
What is the test for C-X in halogenoalkanes
the hydrolysis followed by the silver nitrate test to identify halide ions
What is the test for -COOH in carboxylic acids
pH<7
The tests for alcohols, aldehydes and ketone have what in common
Comparing their ease of oxidation
What is the m/z ration of a molecular ion equal to
the value of the compounds relative molecular mass
What does high resolution mass spectrometry enable
the empirical formula to be worked out
What does infrared radiation do to molecules
It’s absorbed by them causing the molecules to vibrate more rapidly
How can an infrared spectrum be obtained
by measuring the trasmittance of infrared radiation through a sample of material
What do different functional groups absorb different amounts of
infrared radiation
What can an infrared spectrum be used to do
identify that compound
