Question
Which of the following sequences represents the correct decreasing order of reactivity towards electrophilic aromatic substitution?
Answer: B
💡 Solution & Explanation
The activating ability order is: $-OH$ (strong activator) > $-CH_3$ (weak activator) > $-Cl$ (weak deactivator) > $-NO_2$ (strong deactivator). Thus: Phenol > Toluene > Chlorobenzene > Nitrobenzene.
