Question
Chapter 3.3, Problem 10E
a)
Interpretation Introduction
Interpretation:Whether an impurity always lowers melting point of organic compound is true or false should be determined.
Concept introduction:Melting point is temperature that involves conversion of substance from solid to liquid state. Both liquid and solid phases are present in equilibrium with each other at this temperature.
b)
Interpretation Introduction
Interpretation:Whether sharp melting point for crystalline organic substance always indicates pure single compound is true or false should be determined.
Concept introduction:Melting point is temperature that involves conversion of substance from solid to liquid state. Both liquid and solid phases are present in equilibrium with each other at this temperature.
c)
Interpretation Introduction
Interpretation:Whether addition of compound A that does not lower melting point of compound Xso Xis identical to A is true or false should be determined.
Concept introduction:Melting point is temperature that involves conversion of substance from solid to liquid state. Both liquid and solid phases are present in equilibrium with each other at this temperature.
