what is the order of stability of the given compoundCh2: Ch3Ch: C6h5Ch:(C6h5)2Ch:where 'c:'indicate a carbeneRecpected sir please give it answer with details and thanks for answering my last question

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
