Answer 1

③ [ Rate = K [t-Buber] Explanation :- (CH3)₂C-B + H2O (CH3c-oh Reaction occans with sNi mechanes. Rato determining step: (432 - Br slow ans en in Rate = 1 {rusc-] cng ) (D) Nuchophiles are Lewis acids) Explanations - Actually, nuchophils are Lewis bases (2) D) tak butys bromide and NaOH in omso @ → AT 3 > B92 Explanaties; Willain sons Syntheois CSN2) Explanation - 3° allge halich will form Corbootion which is presence of base give alkene.
