dear praveen,


stablity of carbene is governed by two effects ,


1)hyperconjugation


2)resonance


structure in which resonance is possible will have greater stablity ...


structure having more resonating structure will have more stablity...


those in which resonance is not possible , calculate no of alfa hybrogens for assymetric carbon(c:) ....more no of alfa H's more will  the stablity ...


(C6H5)2C:  (7 resonating structure)    >    (C6H5)C:H  (4 resonating structure)                


CH3C:H     (3 alfa hydrogens)           >    C:H2             (0 alfa hydrogens)


stablity order :      (C6H5)2C: >  (C6H5)C:H > CH3C:H > C:H2
