Spectra Problem 6: Use Spectra to Identify the Structure of an Unknown

I am pretty sure that the middle answer has to be mono-substituted because I have tried all of the other answers. The numbers range from 2-8.

Part B

You have just determined that the peaks around 7 and 8 ppm were generated by hydrogen atoms of a benzene ring. You can use this information to determine the number of substituents on the benzene ring as well as their relative position to each other.

What would be the expected substitution pattern of this ring?

Match the words in the left column to the appropriate blanks in the sentences on the right. Make certain each sentence is complete before submitting your answer.

Incorrect; Try Again; 2 attempts remaining

You filled in 3 of 3 blanks incorrectly. There are two peaks and each peak integrates to an equivalent of two hydrogen atoms. Compare these numbers to the molecular formula to determine the true number of hydrogen atoms that generated these peaks.

Explanation / Answer

four

two

para substituted
