Answer 1

ination of this artituted flere anti ACH АВр Elimination of this H leads to NO OCHCH. more substituted product 3 - ? CH3CH2OH and it is also ante coin.t the healing 1 group Br u Br. 113 e Büny.com, CI + Eton. This is an E elimination reaction. Nadet is not a bulky lease so it will abstract that proton leading to more substituted alkene (..e Zaitsere product). Also the elimination should lee anti. are the fa-hydrogen should be ante coith respect to the eliminating Br group NOCH CH3 енен, ОН Heat - Song -> C elly + F1 on Here also the beaction proceeds in Ez elimination and since NaOet is not a bulky base, so it leads to more substituted alkene. > CH3

ACH o n +(MgCOD, WTH c(eus), itd Here this beaction follows the Ez mechanism. But koc(eu), being a bulky base it accomodate the pain hydrogen from the more Borges storically conjested side, aa Heme, nather will take up a proton of soin the less hindened side. Hence it cannot take up that proton from that carbon where which has à CH3 group and also this CH3 group üs not in anti allignment with bespect e leaving group Br. So Be (CH3)₂ took up deuterium from the position which is sterically less hindered and also a ante periplanan with respect to the leaving groupo Bra. Mo d el
