What effect does a nitro group (-NO 2 ) have on the electron density in the benzene ring?

Options

  1. AIt increases the electron density.
  2. BIt has no effect on electron density.
  3. CIt decreases the electron density due to its strong -I effect.
  4. DIt decreases the electron density due to its strong +I effect.

Correct answer

C. It decreases the electron density due to its strong -I effect.

Step-by-step solution

The nitro group (-NO 2 ) decreases the electron density in the benzene ring due to its strong electron-withdrawing (-I) effect.
