- 3. A student is trying to identify an unknown solid based on its melting point. She noted that the compound began to melt at 172°C and finished melting at 177°C. Knowing it is possible for there to be impurities in the sample, is this compound more likely to be camphor or hydroquinone. Explain your reasoning. 4. A young chemist has synthesized what he believed to be acetaminophen. He measured the melting point of this newly formed compound to be 163-178°C. If the literature value for the melting point of acetaminophen = 169-170.5°C, would the young chemist be wise to consume this product for headache relief? Why or why not?What aspects of the structure of indigo contribute to a high melting point? Draw a resident structure of indigo to illustrate your explanation. Indigo H. NaOH H + 2 NO2 H.
