Hexachlorobenzene has a literature melting point of 231 ºC. What would be a reasonable result when melting an impure sample of hexachlorobenzene? It would start melting around 229 ºC and finish melting around 233 ºC. It would start melting around 225 ºC, and finish melting around 230º C. The impurity would melt at whatever temperature is normal for that impurity, but the hexachlorobenzene would melt right at 231 ºC . It would melt right at a temperature lower than the...
