Question

The melting range of 4-nitrobenzyl alcohol is reported as 92-94 degrees C nd the melting range of triphenylmethane is reported as 92-94 degrees C. Which sttment most accuratly reflects the expected results for the melting range of a 50:50 mixture of the two? A. The mixture will hve a sharp melting point above 94 degees C. B. The mixture will melt over a broad temperature range below 94 degrees C. C. The mixture will have a melting range of 92-94 degees C. D. The mixture will have a sharp melting point below 92 degees C.

Explanation / Answer

The above two statements are justified in a 50:50 mixture.the two compounds 4-nitro benzyl alcohol and trimethyl ethane have same melting points.

The Statement B is most accurately reflects the 50-50 micture will have a broad temperature range below 940C

this is due to a weakly acidic solution and a neutral solid compound are mixed together and the change in the physical and chemical properties and the physical property melting and boiling points changes.
