Answer 1

Date : Fehr, is a lewis acid - Bo-Br - fesa +Bra les ebry cenplen will react with electron con phenelas le 41 l 2013 C43 OH is the elecken denating group anol ortho position is nuclesplictic to attack the electrophilic Br-Br - resor comples. methyl group is elecken denating group as because of hypescenjugation hyper conjugation as the effect of delocalisation of electens with the participation of bands of a character It is o, para directing OH is also og para directing since para position are blacked Хо products will be soomeal. Either for will go oetho to oh or outw to CH₃ in major product diect recting

Resmance 7 hyper cay gation Inductive and OH has ortho stars th effect to OH. . so the in Bo - febr, CRR 2 1 or Bm olt febr HB2 major product.
