Carbon-13 NMR

Question 1

Is there splitting in 13C NMR

Answer 1

No splitting

Question 2

Is the area of signal related to number of 13C atoms

Answer 2

No

Question 3

What is carbon 13 NMR

Answer 3

Analyses the different carbon environments in a molecule, dif environs are shown as peaks at dif delta values

Question 4

Which way is x axis in spectra

Answer 4

Reverse

Question 5

What does molecule symmetry mean and example

Answer 5

Molecules that have symmetry so carbons in same environ may display fewer peaks than the no carbon atoms in the molecule eg hexan-1,2-diol has line of symmetry so 3 peaks but 6 carbon atoms in molecule
