I need help in melting point determination. There is a question: The mixed melting points of pairs of the
following compounds were determined:
Compound A (56.5 - 57.2o C); Compound B (56.3 - 57.0o C); Compound C (56.2 - 57.1 o C).
B+C melts at 56.3 - 57.0o C and A+B melts at 45.1- 53.8o C. Which compounds are the same and which compounds are different? What will be the mixed melting point of A + C?
