Provide a resonance structures which explain why ortho and para nitrophenol are much more acidic than phenol
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
2. Using resonance contributors for the intermediate carbocation, explain why a phenyl group is an ortho-para director. FeCl3 + Cl2
Explain why the different positions have different pKa values, using resonance structures. The pka of phenol (C6H5OH) is 10.0. When a nitro group (NO) is attached to the ring, the pka decreases. Explain why the different positions have different pka values, using resonance structures. OH OH OH - ၄ NO, NO₂ 10. 0 pK, = 7 .23 8.35 7.1
director in an EAS reaction . Use the structures Of all of its resonance contributors to support 2. Explain why anisole is an ortho-/para- in your written your answer Refer to structures explanation. 20 20 CH₃ 6/20
3. Draw all possible resonance structures for aniline. Relate the resonance structures to why it is an ortho/para director. 3. Drawhy it is нони 19 Pa
In nitration of acetanilide(synthesis of p-nitroaniline) main product is ortho and para. Explain why ortho and para product is major in resonance and mechanism term.
Label the following as activating (A) or deactivating (D), and then also as ortho/para directors (OP) or meta directors (M). Write the answer below each group. N "Here with other ty A/D? = = = = OP/M? = f) Using resonance structures, explain why a nitro group is "meta-directing" (i.e. does the nitro group actually affect the meta positions?) g) As mentioned in class, the halogens are a bit anomalous as substituents on the aromatic ring: they are deactivating groups,...
write resonance structures for the ortho and para arenium ions formed when ethylbenzene reacts with a Br+ ion (as formed from (Br2/FeBr3)
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.
