(Multiple Choice: Only one answer is correct, and only one answer can be selected) 145153C157159C152157C 15 points You suspect a given substance, unknown X, to be either pure acetaminophen (melting point =169C ) or pure 1,4 dihydroxybenzene (melting point =172C ). Subsequently, you perform a mixed melting point analysis by making the following three samples that yield the results below: Unknow X alone yielded a melting range of 165169C - Unknown X mixed in a 50/50 ratio with acetaminophen yielded a melting range of 154162C - Unknown X mixed in a 50/50 ratio with 1,4-dihydroxybenzene yielded a melting range of 169172C Given the data above, what is the identity of unknown X ? (Multiple Choice: Only one answer is correct, and only one answer can be selected) Neither acetaminophen or 1,4-dithdroxybenzene Actaminophen 1.4-Ditydraxyberzene
