Question

AICI3 CO2H CoCI A. B. C. D. A. D. D 43. Which of the following statements is (are) true about electrophilic aromatic substitution? A. The methoxy group,-OCH3, is an o, p activator because of a strong electron donating B. The methoxy group, -OCH3, is an o, p director because of a strong electron withdrawing C. The methoxy group, -OCH, is an o, p activator because the O atom is an electronegative D. Both statements (The methoxy group,-OCHs, is an o, p activator because of a strong resonance effect. inductive effect. atom. electron donating resonance effect) and (The methoxy group, -OCH3, is an o, p activator because the O atom is an electronegative atom) are true. E. Statements (The methoxy group, -OCHs, is an o, p activator because of a strong electron group, - OCHs, is an o, p director because of a donating resonance effect), (The metho strong electron withdrawing inductive effect), and (The methoxy group, -OCHs, is an o, p activator because the O atom is an electronegative atom) are all true statements.

Explanation / Answer

43) option D is correct

Explanation: -OCH3 is an o,p-activator because of more electron donating resonance effect and because of the more electronegative oxygen atom.
