FREE Expert Solution

Use the table below as a guide for the functional groups present: 

Analyze the given spectrum: 

  • It has a peak at 1700 cm-1 meaning it must contain a carbonyl or more specifically, a ketone. 
  • There is also a short cluster of peaks around 2900 cm-1, which correspond to the sp3 C-H bonds.
  • There are no peaks at around 3100 cm-1 so it could not have sp2 C-H bonds which indirectly says that it does not have double bonded carbons.
