5) Levothyroxine (containing 4 iodine atoms), an important prescribed medication, is a form of thyroid hormone thyroxine. It is a very important drug that is used to treat patients with thyroid hormone deficiency (hypothyroidism). List all the IR diagnostic peaks for Levothyroxine below by approximating the frequency of IR absorption (in cm ¹) for each functional group on the drug (list them below). Ignore the fingerprint region if it is not important НО. int NH₂ OH
Assignment 2 1- While cleaning out a laboratory shelf, you have made a mistake in labeling two bottles of propanol and propanone.
