Which of the following exhibits aromaticity:
(i) Cyclo - octatetraene (ii) Cyclopentadiene (iii) Tropylium cation?
Is benzene same as 1, 3, 5-cyclohexatriene?
No benzene is not same as 1,3,5,-cyclohexatriene.
In 1, 3, 5-cyclohexatriene, there are three C = C having a bond length 134 pm and three C - C having a bond length 154 pm. In benzene, all the six C-C bonds have the same bond length 139 pm. Thus, benzene is not same as 1, 3, 5-cyclohexatriene.
