WebFor CH3, free radical hybridization is sp2, but why is CF3 sp3? It happens because the F atoms are more electronegative than the H atoms so they take away the electron density from the C-F bond and place it more towards the F atoms. So the corresponding orbitals used by C need to have lesser s character hence sp3 is preferred. 2 Quora User WebIUPAC Standard InChI: InChI=1S/CF3/c2-1(3)4 Copy.

Having three σ bonds in a similar manner to CH3· free radical, CF3· should also have sp2 hybridisation. However, if we look at its shape, it is pyramidal and not planar like CH3· free radical (which is sp2-hybridised), which signifies that CF3· should have sp3 hybridisation. mlb clothing for kidsWebJan 23, 2024 · Jan 22, 2024. In chemistry, a radical (more precisely, a free radical) is an atom, molecule, or ion that has unpaired valence electrons or an open electron shell, and therefore may be seen as having one or more "dangling" covalent bonds.
