Sort the following molecules by whether the substituent group is ortho/para or meta directing for electrophilic aromatic substitution.
Homework Answers
The substituent groups - COOH, -NO2, -SO3H, are deactivating the benzene ring by reducing the electron density on benzene nucleus by -M effect/-I effect and are meta directing groups towards aromatic electrophilic substitution.
The groups -CH2CH3, -NH2 are activating groups by increasing the electron density on benzene nucleus by +M/+I effects and thus are ortho and para directing groups.
The group -Br is deactivating by -I effect and directs incoming electrophile into ortho asnd para positions due to +M effect which is weaker than in inductive effect.

Objectives - Section 1 • Identify a substituent as an ortho para director or a meta director, Draw the resonance structure that explains the relative directing ability of a specific substituent. Classify a substituent as an activating or a deactivating group. Explain why the halogens are ortho/para directors but are deactivators. • 1. Draw the mechanism of the reaction below and use resonance structures of the arenium ion intermediate to explain why the starting material is an ortho/para director
