Problem: The following IR spectrum is for hexyl acetate. Identify what the major peaks in the spectrum represent (carbonyl, ester, alcohol, etc)?

FREE Expert Solution

Given: hexyl acetate 

  • hexyl → R = 6 carbons 
  • acetate → ester (RCOOR')
    • R' = acetate

Characteristic IR spectrum values:

  • alkane C-H stretch → 2990 – 2850 cm-1
  • Esters 
    • C=O stretch
      • 1765 – 1735 cm-1 (sat.)
      • 1730 – 1715 cm-1(conj.)
  • Alcohol (OH stretch) → 3550 – 3200 cm-1 not present
