Arrange the following compounds in the decreasing order of reactivity towards electrophilic substitution reaction.
(I) Chlorobenzene
(II) Nitrobenzene
(III) Benzene
(IV) Isopropylbenzene
- A \(\mathrm{I}>\mathrm{II}>\mathrm{IV}>\mathrm{III}\)
- B \(\text { IV }>\text { III }>\text { I }>\text { II }\)
- C \(\mathrm{IV}>\mathrm{I}>\mathrm{II}>\mathrm{III}\)
- D \(\mathrm{III}>\mathrm{II}>\mathrm{IV}>\mathrm{I}\)
Answer & Solution
Correct Answer
(B) \(\text { IV }>\text { III }>\text { I }>\text { II }\)
Step-by-step Solution
Detailed explanation
The reactivity of benzene derivatives towards electrophilic aromatic substitution depends on the nature of the substituent attached to the benzene ring. Electron-donating groups (EDG) increase the electron density of the ring, making it more reactive, while electron-withdrawing…
