The order of stability of the species (i), (ii) and (iii) is

A

`(iii)gt(i)gt(ii)`

B

`(iii)gt(ii)gt(i)`

C

`(ii)gt(iii)gt(i)`

D

`(i)gt(iii)gt(ii)`

Text Solution

Verified by Experts

The correct Answer is:
1
(iii) is aromatic as it is planar and has `(4n+2)pi` delocalized `e^(-)s` (i) is nonoaromatic as it is nonplanar and has `4npie^(-)s`. (ii) is antiaromatic as it is planar and has `4npie^(-)s`.
