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
