Consider the possibility that an organic molecule X with a melting point of 140oC is o-chlorobenzoic acid. The melting point of a combination comprising approximately equal amounts of X and an authentic specimen of o-chlorobenzoic acid can be determined to determine its identity (A). If the m...
Consider an organic compound X having a melting point of 140oC is suspected to be o-chlorobenzoic acid. Its identity may be established by performing a melting point determination of a mixture containing approximately equal weights of X and of an authentic specimen of o-chlorobenzoic acid (A)....
What is the effect of an impurity on the melting point of a solid? Why does urea have a sharp melting point but glass does not? Why does chlorobenzoic acid have a lower freezing point than benzoic acid? Explain. How does the appearance of the impure solid ben...
