Topic 26- NMR spectroscopy Flashcards
1
Q
Why are CDCl3 and CCl4 good for H NMR spec
A
Both goos solvents
Inert
Both have no H atoms
CCl4 is non polar- good for non-polar organic molecules
CDCl3 is a polar covalent molecule so it is a good solvent for polar organic compounds

Q
Why is TMS a good standard for H NMR spec
A
TMS has a peak at 0 so is a good standard
Signal away from typical H signals
Easy to remove as it is volatile with a low boiling point
