Question

1. The formula for salicylic acid is C-H.O, calculate its cesof unsaturation 2 The formula for Aspirin is CoH,O, calculate its degrees of unsaturation 3. Draw the structures of salicylic acid and acetylsalicylic acid (Aspirin) and circle areas of un 4. What would the parent ion would you expect for both compounds. What would be the most likely daughter ion peaks for both compounds? Salicylic Acid Acefylsalicylic Acid (Aspirin) Acetylsalicylic acid and Salicylic acid. Identify which spectra is the attached MS spectra for resulting in those aluate hel at least 3 daughters ions. Predict the potential fragments lost resulting which and label at le

Explanation / Answer

Degree of unsaturation:
Degree of unsaturation = (2C + 2 + N - H - X)/2
Where C is number of carbon
Where N is number of Nitrogen
Where H is number of hydrogen
Where X is number of halogen

1)
Degree of unsaturation = (2C + 2 + N - H - X)/2
=(2*7 + 2 + 0 - 6 - 0)/2
=(10)/2
= 5
Answer: 5

2)
Degree of unsaturation = (2C + 2 + N - H - X)/2
=(2*9 + 2 + 0 - 8 - 0)/2
=(12)/2
= 6
Answer: 6
