Which of the following is the most activating in electrophilic aromatic substitution?
Correct answer: D. NH2
- A. NO2
- B. NHCOCH3
- C. CN
- D. NH2
Explanation
The most activating group in electrophilic aromatic substitution is NH2. Electron-donating groups, such as NH2, make the aromatic ring more reactive towards EAS by donating electrons to the ring. The other options - NO2, NHCOCH3, and CN - are all deactivating groups that cannot undergo electrophilic aromatic substitution.

About Chemistry of Hydrocarbons
Hydrocarbons are studied through the structures and reactions of alkanes, alkenes, alkynes and aromatic compounds. Coverage includes free radical substitution in alkanes, electrophilic addition to carbon-carbon multiple bonds, benzene substitution, aromatic stability and the difference between addition reactions of alkenes and substitution reactions of benzene.
