Shape of cf3 radical
Webb24 sep. 2024 · The carbon atom in the carbocation is electron deficient; it only has six valence electrons which are used to form three sigma covalent bonds with the substituents. The carbocation carbon has an unoccupied p orbital which is perpendicular to the plane created by the substituents.

Based on this, a method for the synthesis of α-trifluoromethylated ketones has been successfully developed.
Webb1 feb. 1971 · Their spectrum, which is effectively a photo- electron spectrum of the CF3 radical, shows a long progression of bands each separated by about 830 cm . They assign this as a transition from the pyramidal ground state of CF3 to the planar CF~ ion in which the out-of-plane bending vibration is excited.
