Benzophenone/Melting point
What is melting point range of the organic compound?
0.5-1.0°C
A pure, nonionic, crystalline organic compound usually has a sharp and characteristic melting point (usually 0.5-1.0°C range). A mixture of very small amounts of miscible impurities will produce a depression of the melting point and an increase in the melting point range.

What is the molar mass of Benzopinacol?
366.45 g/mol
Benzopinacol/Molar mass
What is the range for melting point?
1-2ºC
The melting range is defined as the span of temperature from the point at which the crystals first begin to liquefy to the point at which the entire sample is liquid. Most pure organics melt over a narrow temperature range of 1-2ºC, if heated slowly enough.
What is the percentage of N in urea?
46.6%
So, the percentage of nitrogen present in the urea is 46.6%.
Does urea have a high or low melting point?
Urea is a molecular crystal with a melting point of 405.7 K under normal pressure.
What is the melting point of N-phenylsuccinimide?
The accepted melting range for N-Phenylsuccinimide is 155-157 degrees Celsius, so the separation techniques produced an almost pure sample of N-Phenylsuccinimide. The goal of this experiment was to identify an impure organic compound.
What was the melting point of the compound E?
Compound “E” was identified by purifying it through recrystallization with hot ethanol as a solvent and determining it’s melting point. It had a melting range of 154.3-155.5 degrees Celsius. When mixed with known N-Phenylsuccinimide, the melting range was determined to be 154.3-155.3 degrees Celsius.
How is a solvent used to purify N-phenylsuccinimide?
An appropriate solvent was found among water, acetone, ethanol and toluene by doing small-scale solubility tests. To purify the N-Phenylsuccinimide, it was dissolved in hot ethanol, filtered to remove contaminants, and then cooled to reform crystals that were separated from the ethanol by vacuum filtration.
