1. Calculate D.O.U.
2. Identify and draw correct structure.
3. Assign peaks to justify your structure.
Homework Answers
Double on index D.O.U
= 1 that is one double bond present .
IR. .......
Peak at 1741 says presence of carbonyl group.
Peak at 2984 cm-1 says alkane C-H stretching
MASS spectrometry. . .....
Fragment at m/z = 43 means CH3-C=O+
Fragment at m/z = 29 means CH3-CH2+
DEPT 135.......
We get negative Peak due to -CH2 and positive peak for -CH3.
Here one -CH2 present and two - CH3 present.
13 NMR. ....
Four kinds of carbon, peak at 172 ppm shows presence of Ester group.
1H NMR. ....
Three types of hydrogen
3H triplet , 2H quartet , 2H singlet.
Name of the compound is
ethyl-ethanoate
CH3-C(O)O- CH2-CH3
