How can you identify an alcohol with infra-red spectrometry?
a smooth curve at 3230-3550
How can you identify a carboxylic acid with infra-red spectrometry?
a jagged curve from 2500-3000
How do you identify a C=O with infra-red spectrometry?
a sharp peak around 1700
What is below 1500 on an infra-red spectrometer?
the fingerprint region
What does the best greenhouse gas do?
absorb the most infrared radiation and traps heat in earths atmosphere.
How does carbon dioxide cause global warming?
C=O absorbs infrared radiation and the IR emitted from earth doesn’t escape from the atmosphere
Why does carbon dioxide absorb infrared radiation?
C=O bonds vibrate at the same frequency as IR
