WebJan 15, 2024 · Ligand is a molecule or an ion that has at least one electron pair that can be donated. Ligands may also be called Lewis bases; in terms of organic chemistry, they are ‘nucleophiles’. Metal ions or molecules such as BF 3 (with incomplete valence electron shells (electron deficient) are called Lewis acids or electrophiles).
The trifluoromethyl group is a functional group that has the formula -CF3. The naming of is group is derived from the methyl group (which has the formula -CH3), by replacing each hydrogen atom by a fluorine atom. Some common examples are trifluoromethane H–CF 3, 1,1,1-trifluoroethane H 3C–CF 3, and hexafluoroacetone F 3C–CO–CF 3.
