explain what are 1)carbenes 2)carbocations 3)carbanion along with their structures and hybridizations with reasons also explain the increasing stability of these organic compounds.

dear nikhil

carbenes are of two type -

singlet - sp² hybridised

triplet -  sp hybridised

triplet carbene is more stable than singlet carbene...

carbocation is a specie which has +ve charge on carbon atom , this carbon is SP² hybridised ...

there is no lone pair at this carbon..

stablity order = benzyl>allyl>3^o>2^o>1^o

carbanian is a specie which has -ve charge on carbon atom...carbanions are SP³hybridised ...

lone pair remains with this carbon...

stablity order = benzyl>allyl>1^o>2^o>3^o
