2. What are the stretches for Esters, Carboxylic Acids/Aldehydes and Ketones, in that order?

  • 1745,1730,1715
  • 1715,1730,1745
  • 1690,1680,1670
  • 1715,1745,1730

3. What does a peak between 1640 and 1690 mean?

  • Aromatic ring
  • Amide or C double bond C
  • Nitrile group
  • Ketone

4. What do broad OH peaks mean?

  • It's a strong signal
  • Nothing- it's interpreted the same way as a narrow peak
  • There's H bonding present
  • There's a lot of OH bonds

5. What is the stretch for NH2?

  • 1350- symmetric and 1530-antisymmetric
  • 3300-symmetric and 3400- antisymmetric
  • 3000 for both
  • 3200-symmetric and 3100-antisymmetric
