             All compounds actuallymelt over a range rather than at a single temperature, thereforereporting a melting range is simply stating what is actuallyobserved. Other than this, why should a melthing range rather thana melthing point always be reported?              All compounds actuallymelt over a range rather than at a single temperature, thereforereporting a melting range is simply stating what is actuallyobserved.

Explanation / Answer

melting range is from where the material is expected tostart & complete the process of melting. whereas melting point is the average to the max and the min ofthe melting process. thus reporting the range is more complete and accurate. Whereas finding a melting point for a compound with a reasonable rangeis prone to error and hence pointless. The correct method is notingthe maximum and minimum ie end and start of melting and then takethe average to get melting point. whereas melting point is the average to the max and the min ofthe melting process. thus reporting the range is more complete and accurate.
