Which of the following compounds will show the highest reactivity towards electrophilic aromatic substitution?
- A.
- B.
- C.
- D.
Show correct answer & step-by-step solution
Correct answer: C —
Solution
- Electrophilic aromatic substitution reactivity depends on the electron density of the benzene ring.
- Electron-donating groups increase electron density, while electron-withdrawing groups decrease it.
- The methyl group in toluene is an activating group due to the effect and hyperconjugation.
- Nitrobenzene is strongly deactivated, while chlorobenzene is weakly deactivated.
- Hence the answer is (C).
