Your TA gave you 1 H NMR spectra of your product and iodotyrosine. Using the 1 H NMR spectra and the data given in the special section (p44 and 45), determine the structure of your product - i. E. Do you have ortho-bromo-4-tert-butylphenol, or meta-bromo-4-tert-butylphenol? Explain (using the 1 H NMR) how you came to your decision
