What is the melting point of meso-stilbene dibromide?

Answer 1

The meso isomer, which has a mirror plane down its vertical symmetry axis, would be the #("R","S")# stereoisomer, because mirroring the #"R"# configuration gives you the #"S"# configuration.

So, it looks like either of the above structures.

Based on the following references, I see that the melting point RANGE is close to #241^@ "C"#.

I used Scifinder and found two probable melting point ranges:

#239^@ ~ 241^@ "C"#
Schroth, Werner; Zeitschrift fuer Chemie 1977, V17(2), P56 CAPLUS

#236^@ ~ 237^@ "C"#
Fieser, Louis F.; Journal of Chemical Education 1954, V31, P291-7 CAPLUS
Yusubov, M. S.; Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya 1991, (4), P868-73 CAPLUS)

And additional references also say about #241^@ "C"#.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
