Melting Point for Known Compounds
C. Which is to be, X (listed mp 97-98 Ë?
C) or candidate Y (listed mp 86-87 Ë?
C). Why might your sample not have the same melting range as either of the known compounds, given that it must be one of them?
* Test tubes labeled A, B, and C contain substances with the same melting points. How could you prove (using the melting point technique) the test tubes contained three different chemical compounds?
