#1
Front (Question)

Why can’t a high resolution mass spectrometer tell the difference between propan-1-ol and propan-2-ol?

Back (Answer)

same m/z for molecular ion peak so the molecular mass will be exactly the same.

#2
Front (Question)

Why does C have a relative molecular mass of 12.00000?

Back (Answer)

12C is the standard reference

#3
Front (Question)

What does the OH bond in alcohols look like on the mass spec?

Back (Answer)

1 finger profile test tube (state the bond length)

#4
Front (Question)

What does the OH bond carboxylic acids look like on the mass spec?

Back (Answer)

4 finger profile jagged (state the bond length)

#5
Front (Question)

What does a C=O bond look like on the mass spec?

Back (Answer)

sharp spike (state the bond length)

#6
Front (Question)

What is the fingerprint region?

Back (Answer)

the area of the spectrum that is below 1500cm-1.
