Question

Please answer the exercise 9.2. I have included the spectrums. Please review attached images and table to help answer questions. Match the compounds to their corresponding spectrums. Thank you very much!

Match each spectrum in exercise 9.2 of your text (pages 449-450) to a compound on the right. Remember that you can use Table 9.2 on page 439 to solve these puzzles along with some of the reading. cycloheptene H2N 4-methylaniline CI p-dichlorobenzene ethynylbenzene 3-methylphenol odobenzene Choose...
