The stability order of carbocation is :
The stability order of carbocation is II > III > I > IV
II = resonance stabilise with 2pi bonds
III = resonance with one pi bond
I = hyperconjugation 4αH
IV = anti aromatic
The correct order for decreasing stability of the following free radicals is
Arrange the following carbocations in decreasing order of stability
The stability of carbanions in the following
i) RC≡⊖C
ii)
iii) R2C=⊖CH
iv) R3C−⊖CH2
is in the order of
