6. The correct order of stability of given carbocations is
(1) I > IV > III > II (2) I > IV > II > III
(3) IV > I > III > II (4) IV > I > II > III
Dear Student,
The stability of carbocation is benzylic carbon > allylic carbon > tertiary > secondary > primary.
The reason is benzyl carbocations are more resonance stabilised than allyl.
Tertiary carbocations have three +I alkyl group which stabilises the carbocation more than the secondary which has only two which in turn is more than the primary as it has only one carbocation.
For the question given the answer is (4)
