which one of the following is most reactive towards electrophilic attack?

Solution

Electron releasing groups stabilise the intermediate cation whereas electron withdrawing groups destabilise it.
The order of electron withdrawing group is:
NO₂ > Cl >OH> C₆H₅
Hence is more reactive_towardselectrophilicsubstitution because -OH group least destabilise the carbocation. Further -OH group is strongly activating group while -NO2 and -Cl are deactivating group.
