problem 1

DUE: at the beginning of your final 1. You are assigned to identify an unknown sample. A preliminary melting point suggests that it is either naphthol (121-123°C) or benzoic acid (122-124°C) or benzamide (127-128C). Explain how you could narrow the list and positively identify the sample (2 pts). 2. You are synthesizing salicylic acid from methyl salicylate. You combine 0.30 mL of methyl salicylate and 0.52 g sodium hydroxide in water and heat. CH OH 2. H,SO4 (a) What is the theoretical yield for this reaction (1 pt)? (Show your work.)

Explanation / Answer

If your compound gives gas (carbon dioxide) with NaHCO3. Then your compoound is benzoic acid.

If your compound gives positive FeCl3 test. It is napthol.

If your compound give negative test with NaHCO3 and FeCL3 test. Therefore the compound is Benzamide.
