WILLUDUlyalli Clemsty ENAM 20. Explain why Compound A is more acidic than Compound B. Use resonance structures to e 21. Which of the following is the least stable carbocation? Circle your response. (2) IV
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
Why can phenoxide's negative charge only be stabilized through resonance in the ortho/para position but not the meta position? Provide a drawing to explain your answer.
