Electron Withdrawal (-M): The Nitrobenzene Effect

The video explains the minus M effect, where atoms or groups withdraw electrons, focusing on the Nitro group in nitrobenzene. The Nitro group, with a positive charge, is bonded to oxygen, affecting the benzene ring's electron density. This interaction leads to resonance, forming specific structures and reducing electron density at ortho and para positions, making nitrobenzene less reactive to electrophilic attacks compared to benzene.

What is the minus M effect and how does it relate to the Nitro group in nitrobenzene?

Explain the role of the nitrogen atom in the Nitro group when attached to the benzene ring.

How does the minus M effect influence the electron density of the benzene ring?

What are the consequences of the decrease in electron density in the benzene ring due to the Nitro group?

Why is nitrobenzene less reactive than benzene towards electrophilic attack?
