It generally abbreviated and literally always called DMF should not be mistaken with dimethylfuran or dimethyl fumarate. Of course boiling point relationships may be dominated by even stronger attractive forces such as those involving electrostatic attraction between oppositely charged ionic species and between the partial charge separations of molecular dipoles. D7398 - 112021 Standard Test Method for Boiling Range. Its at that point that you need to learn understand the relative reactivity of different functional groups their compatibility with different reagents and also how to plan a synthesis such that only one key functional group will participate in the reaction. Next Post Thiols And Thioethers.
