A student in 51LA conducts a melting point experiment with an unknown
compound and observes a melting range of 122 – 129 °C. Is this a typical
range for a melting point? If not, what range would be typical?
Well for a pure compund the meliting range is from .5 to 2.0C. I think the range of 122-129 C is too high. I'm I right?

what is the typical melting range of a compound? I think .5 to 2.0 C is way tooo low.

I always used a range of 1-2o C.

Yes, you are correct. The observed melting range of 122-129 °C is higher than the typical range for a pure compound. The typical range for a melting point of a pure compound is generally smaller and falls within a range of 0.5-2.0 °C. Therefore, the melting range of 122-129 °C indicates that the compound being tested is likely impure or a mixture of multiple compounds.
To determine if a melting point range is typical or not, one would need to compare the observed range with the known melting points of similar compounds or consult reliable references such as scientific literature or databases. These sources provide information on the melting points of various compounds and can be used to assess whether the observed range is within the expected range for a specific compound.
