Question
Identify the correct order of reactivity in electrophilic substitution reactions of the following compounds :
1 2 3 4
1 2 3 4
Options
A.1 > 2 > 3 > 4
B.4 > 3 > 2 > 1
C.2 > 1 > 3 > 4
D.2 > 3 > 1 > 4
Solution
Any electron donating group, when attached to benzene fing will activate it towards E+ - subatitution . On contrary electron with drawing droups will deactivate it towards E+ - subatitution
Because - CH3 is electron donating (So activating) gp. while - Cl and - NO2 are electron withdrawing. Also effect of - NO2 is more than.
