Question

Consider the following carbocations

The correct increasing order of stability of these carbocations is:

(1) (i) < (ii) < (iii) < (iv)

(2) (iv) < (iii) < (ii) < (i)

(3) (ii) < (iii) < (iv) < (i)

(4) (iv) < (iii) < (i) < (ii)

Answer 1

Correct option is : (2) (iv) < (iii) < (ii) < (i)

Tropylium carbocation is most stable due to presence of aromaticity.

\(\therefore \) (i) > (ii) > (iii) > (iv) is the correct order of stability of carbocation.
