"My teacher had mentioned that resonance would occur here due to the presence of a positive charge if benzene is attached. However, if we consider two bonds without breaking them, there will be one pi bond. So, will there be no resonance due to it?"

Though I am a layman on quantum chemistry, benzene (C6H6) is negatively charged inside the ring, and positively charged on the outside. The Pi electrons in NO2 tends to be attracted to benzen and have some tendency to break. The resonance would be incorborated into total bond strength.

Your question is not clear. Could you rephrase it?

Resonance is ubiquitous in conjugated pi bonds.
 

FAQ: Does Resonance Occur in Nitrobenzene Despite Having One Pi Bond?

Does resonance occur in nitrobenzene despite having one pi bond?

Yes, resonance does occur in nitrobenzene despite having one pi bond. The nitro group in nitrobenzene can delocalize the electrons through resonance, leading to a more stable molecule.

How does resonance affect the stability of nitrobenzene?

Resonance increases the stability of nitrobenzene by delocalizing the electrons within the nitro group. This delocalization spreads the charge over a larger area, making the molecule more stable.

What is the role of the nitro group in resonance in nitrobenzene?

The nitro group in nitrobenzene plays a crucial role in resonance by accepting and donating electrons through its nitrogen and oxygen atoms. This electron delocalization leads to resonance stabilization of the molecule.

Can resonance in nitrobenzene affect its reactivity?

Yes, resonance in nitrobenzene can affect its reactivity. The delocalization of electrons through resonance can influence the reactivity of nitrobenzene towards electrophilic aromatic substitution reactions.

How does the presence of a pi bond impact resonance in nitrobenzene?

The presence of a pi bond in nitrobenzene allows for the delocalization of electrons through resonance, enhancing the stability of the molecule. This delocalization is facilitated by the presence of the nitro group in nitrobenzene.
