The order of stability of aromatic hydrocarbons given bwlow is

Options

A. `A lt D lt B gt C`
B. `D lt A lt B lt C`
C. `B gt C gt D gt A`
D. `A gt D gt B gt C`

Answer

D

Explanation

Given,
Aromatic hydrocarbons

Resonance energy per ring for `A = 36K` cal/mol
`B = (61)/(2) = 30.2K` cal/mol
`C = (84)/(3) = 28K` cal/mol
`D = (92)/(3) = 30.5` K cal/mol
Since stability of aromatic compounds ` alpha` Resonance energy per ring
`therefore A gt D gt B gt C`
