Analytical techniques Flashcards
1
Q
what to look for in IR spect
A
.pointy dip at 1700 = C=O bond
.broad dip after = O-H bond
spikey dip after = C-H bond
.contains both = carboxylic acid
.has only C=O = ketone/aldehyde
2
Q
mass spect
A
.sample is ionised by firing electrons at it
.accelerated through an electric field
.deflected through magenetic field
3
Q
what to look for in mass spect
A
last peak = molecular ion peak = 1 electron knocked off = Molar mass
