Ethylenediamine polarity

Tetramethylethylenediamine (TMEDA or TEMED) is a chemical compound with the formula (CH3)2NCH2CH2N(CH3)2. This species is derived from ethylenediamine by replacement of the four amine hydrogens with four methyl groups. It is a colorless liquid, although old samples often appear yellow. Its odor is similar to that of rotting fish. WebChemistry questions and answers. RECRYSTALLIZATION LAB (ORGANIC CHEMISTRY) Methanol will not be a good solvent for the recrystallization of Fluorene. (Fluorene dissovles immediately at room temperature.) Water is not a good solvent for the recrystallization of Fluorene. (Flourene doesn't dissolve at room tempurate or at the boiling point of water.)
