Which of the following will not easily undergo Friedel Crafts reaction?
Correct answer: B. Nitrobenzene
- A. Xylene
- B. Nitrobenzene
- C. Cumene
- D. Toluene
Explanation
Friedel-Crafts reactions require an electrophile to attack an aromatic ring. Nitrobenzene contains a nitro group, an electron-withdrawing group that destabilizes the aromatic ring by withdrawing electrons. This makes it less reactive towards electrophiles and thus does not easily undergo Friedel Crafts reaction. Xylene, Cumene, and Toluene all contain electron-donating groups which stabilize the aromatic ring and make them more reactive, hence they can easily undergo Friedel Crafts reaction.

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.
