Question

Which is more stable? Position A/ Position B (circle one) COOH COOH Which is more stable? Position A/ Position B (circle one) 9. Given the results of the previous problems, if an ELECTRON DONATING group is already attached to benzene, it is more stable to add the electrophile to the _position(s). Look at positions A and B in the previous problems. a. Ortho b. Meta C. Para d. Two of the above e. None of the above 10. If an ELECTRON WITHDRAWING group is already attached to benzene, it is more stable to add the electrophile to the position(s). a. Ortho b. Meta c. Para d. Two of the above e. None of the above

given

Answer 1

Big) og Gs effet) S- i if & B is electrophile it will attack ortho . position so that now if Bis nucleophile the reaction will be show or may not take place =) stable cooh Cu =) -eoot has -R effect that is . cooh withdrawas electron co eow Õ, Olt õi z on -0H Now if Ais nucleophile inly then the reaction will take place and will attack on ortho position COOH HO A wills t A stable At 9) My I CA Electron ( RTO Cortho) th (para) donating group) Electrophile - The answer will be d.) Two of the above corths of para),

ut # 1 11 Ew , Electron E Bw Cortho) withdrawing (parra) gombo The answer coill be do Two of the above corthas para) 459 2) for As öet, is electron donoting Į to 'stay far away group it stable Bir so -) far away I Methyl group has tI effect mark that makes the coelosest e-atom partially a ve charged and forest -e-atom has been partially the charged so correct option will be 6) far away. 9 No group is electron with drawing group so that et will stay closest . - a. 5) same -No, group-eoot is also electron with drawing group ED Clonest et
