Organic Analysis Flashcards
How do you test for alkenes and what is result
Shake with bromine water
Orange to colourless
How to test for alcohols and what is result
Add acidified potassium dichromate
Orange to green for 1 and 2 alcohols no for 3
How do you test for aldehydes
Tolling or fehlings solution
How to you test for carboxylic acid
Add Na2CO3 which gives off Co2 and limewater can prove it
What is mass spectrometry
Used to find the relative molecular masses of organic compounds
Why do atoms and chemical bonds absorb infrared radiation
They are constantly vibrating so they can absorb infrared radiation that is the same frequency
What effect does a stronger bond have on the frequency of vibration
Vibrate faster (with higher frequency)
What effect do heavier atoms have on the frequency of vibration
Vibrate slower (with lower frequency)
