Question

Got #12 wrong, can you please explain.

(D) OH OH 12. Electrophylic Substitution Reactivity: HO. (A) (B) (C) (D) NO2 13. The Strength of Electrophile: (A) H NO. RA

Answer 1

Benzene nings give Elecinophilic substitul ian neactisn (ESR) Electnophiles (Ee) ane +vely chenged -Benzene is electnon nich species, hence it can easily atlnact towconds itself. >Electrion clonating gnodps (EDG) incn eases the e density of benzene E lectonon withdnqwiny gnoops (EWG) decncases the e" dens 1y of benz ene 9h J1 will incnease the e densily by +R effect EDG -CH3 iimcneass the e densily by +1 cffect +R effect dominales oven +1 effect EWG NO2-7H will decnease the electnon densily by +R effec Hence, MoSie ekectnon nich species Но CH3 Electnon deficient species NG2 The nief on, Onden of ESR (D) Но. но. (A) (B) NO2 This wils not give ESR
