Hey dear,
● Answer -
Decreasing order of reactivity towards electrophilic substitution reactions is -
phenol > 4-bromophenol > 2-nitrophenol > 1,3-dinitrobenzene
● Explanation -
- Reactivity of a compound towards electrophilic substitution is determined by its functional groups.
- Electron donating groups activate the ring. e.g. CH3, OH, etc.
- Electron withdrawing groups deactivate the ring. e.g. NO2, Cl, etc.
- Hence, decreasing order of reactivity towards electrophilic substitution reactions is -
phenol > 4-bromophenol > 2-nitrophenol > 1,3-dinitrobenzene
Hope this helps you.
