Question

Circle T for true statements or f for false statement. spectroscopy Is used to determine molecular weights of organic compounds. The tallest bar in a mass spectrum is known as the bose peak. On a given mass spectrum a methyl radical ( CH_3) would display a bar at m/z = 15. A compound containing C, H & O provides In M = 46. Answer the following questions with respect to this information. Show your work for each problem. What is molecular formula of this compound if contains one oxygen atom? What is the index of this compound? Provide two possible structures that meet the above criteria.

Explanation / Answer

2. For the compound with C, H, and O as its components and M+ as 46,

a. Molecular formula of the compound = 15(CH3) + 15(CH3) + 16(O) = 46

C2H6O

b. The index of this compound = 0

c. Two possible structures for the compound would be,

CH3CH2OH

CH3OCH3
