Distinguish between carbocation and carbanion
Answers
Carbanion is a conjugate base of methane or other hydrocarbon formed by heterolytic cleavage and contain eight electrons 6 are bonded two are nonbonded and carbon is sp3 hybridided having pyramidal geometry.On the other hand carbon radical is formed by homolytic cleavage contain 7 electrons 6 are bonding 1 is non bonding, sp3 or may be sp2 hybridised .Radicals are more reactive than carbanion.carbanion is stabilised by electron withdrawing group whereas carbon radical stabilised by both electron donating and electron withdrawing both.Carbanion also act as good nucleophile whereas radical doesn't.
Hii
hear your answer
CARBOCATION :
1.carbocation is an ion containing a positively charge carbon atom
2.the carbon atom bearing the positive charge is sp2 hybridized
3.the geomety of the carbon atom is trigonal planar
4.paramagnetic
CABANION :
1.carbonion is an ion containing negative charge carbon atom
2.the carbon atom bearing the negative charge sp3 hybridized
3 .the geometric of the carbon atom is pyramidal
4.diamagnetic
