For each spectrum shown below for mass spec, ir, and nmr identify important peak

Q: For each spectrum shown below for mass spec, ir, and nmr identify important peak

Interpretation of spectrum IR 2850-3000 cm-1 peaks for aliphatic C-H stretch 1720 cm-1 for C=O stretch 1H NMR 0.9 ppm (d, 6H) for 2CH3's next to CH 2.0 ppm (s, 3H) for CH3 next to C=O a downfield triplet for 2H is for CH2 next to CH2 and oxygen Mass spectrum gave M+ 130 A possible structure would be thus, (CH3)2CHCH2CH2OCOCH3

Explanation / Answer

Interpretation of spectrum

2850-3000 cm-1 peaks for aliphatic C-H stretch

1720 cm-1 for C=O stretch

1H NMR

0.9 ppm (d, 6H) for 2CH3's next to CH

2.0 ppm (s, 3H) for CH3 next to C=O

a downfield triplet for 2H is for CH2 next to CH2 and oxygen

Mass spectrum gave M+ 130

A possible structure would be thus,

(CH3)2CHCH2CH2OCOCH3
