Question
How many of the given compounds are more reactive than benzene towards electrophilic substitution reaction?
Open in App
Solution
The above given compounds are more reactive than benzene towards electrophilic substitution reaction.When electron withdrawing groups such as −NO2, −CCl3 are present on the benzene ring, they decrease the electron density of benzene ring and deactivate it towards electrophilic aromatic substitution reaction. When electron releasing groups such as −OH, −OCH3, −CH=CH2 are present, they increase the electron density on benzene ring and activate the ring towards electrophilic aromatic substitution reaction. Among the given compounds, only five compounds are more reactive than benzene towards electrophilic aromatic substitution reaction. They are shown in the figure.
