    classical carbocation is more stable than non classical carbocation because the energy of a classical carbocation is low compared to the energy of the corresponding nonclassical carbocation. for more detail check the pdf

    ## Alkyl free radicals are either planar or pyramidal in structure.Spectroscopic evidences shows that methyl free radical(.CH3) is planar in shape ,thus it is conveniently described by sp2 hybridisation with the unpaired electron located primarily in p-orbital. But in case of substituted radicals like trifluoro methyl free radical increasing fluorine substitution causes the radical to go from planar sp2 hybridisation ( as in .CH3) to tetrahedral, sp3 hybridisation in (.CF3 )radical. ## Allylic and benzylic cabanions are said to have sp2 hybridization because they lone pairs present on carbon involve in delocalization(Resonance). However delocalization is effective if it has more planar arrangement (which provides maximum overlap). So due to this it is said to have sp2 hybridization.
