Question

hello guys.....
why nitrobenzene is meta directive ?​

Answer 1

Answer:

subscribe my channel AK boys coin collection in you tube

Explanation:

Resonating structure of nitrobenzene shows +ve charge develops in ortho and para positions. As a result, the electron density at meta position is relatively higher than at the ortho and para position. ... HENCE, nitro group is meta directing in electrophilic aromatic substitution reaction..

hope it helps you

Answer 2

Answer:

nitrobenzene is para directing because if you look at the resonance structure then you will find that there is positive charge on para and Ortho position therefore in case of electrophilic substitution and electrophile must attack on the mata position because there is no positive charge present there that's why nitrro group is meta directing with respect to benzene

( because electrophile is a species which attacks mostly on negative charge or place where there is lone pair)
