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. WebAug 17, 2024 · Polar vs. Nonpolar Solvents: Identifications and Examples. Polar solvents are solvents with large dipole moments whereas nonpolar solvents have low or sometimes, no dipole moment at all. The dipole moment arises from polarity which basically comes from the difference in electronegativities of the bonded atoms in a molecule.
