Homework Answers
Degree of unsaturation or degree of hydrogen deficiency is given
by:
DOU = (2C + 2 + N - X - H)/2
X is number of halogens
C is number of carbon
N is number of Nitrogen
H is number of Hydrogen
1)
Use:
DOU = (2C + 2 + N - X - H)/2
= (2*8 + 2 + 1 - 0 - 7)/2
= (19 - 7) / 2
= 6
Answer: 6
2)
DOU = (2C + 2 + N - X - H)/2
= (2*4 + 2 + 1 - 1 - 4)/2
= (11 - 5) / 2
= 3
Answer: 3
3)
DOU = (2C + 2 + N - X - H)/2
= (2*21 + 2 + 2 - 0 - 22)/2
= (46 - 22) / 2
= 12
Answer: 12

During the past two semesters, we have talked about infrared spectros- y (IR), 'H-NMR spectroscopy, "C-NMR spectroscopy, and Mass spec- trometry (MS). We've also talked about using information gathered from the mass spectrum to generate a molecular formula and the index of hydro- gen deficiency which helps us determine information about our compound when there isn't any available.
