Answer 1

Pege No. Date: Reaction of 2- Bromo butane with Nai Jacetone Nail acetone is the reagent used in finkelstein reaction Alkyl haledes are tecated with it. to que alkyl iodides Nace and Nasr au folned which are هجومهم وعليهمر دم CH₂ CH ₂ -CH-CH3 + Nal ocetone CH₃ CH₂ CLM CH₂ + Naubra I act as nucleophill and wants the 2-bromo butane to give 2-Todo. butane Mechanim CH₂ CH₂ CH-CH3 + NO I C H₂CH.

Page No.: YOUVA R Date: 3 carbon. reaction does not accen with wallacetene canly Nalacetne reacts with alkyl haliele by S2 mechanin. - and the reaction is faster where the there is less stearic linderance reaction order. Reactivity oder i 72 73 bromobutane 7 2hrono butuma 2-brome dimethys propone 7 bromo cyclohenone I bromo odmanta fastee with binary halides reacts Nal/acetine Tertiary halides react slowly

2- Bromabutane macts with Ag No, lethanol CH₂ CH₂ CH-CH2 + Ethand holz-C4 - 4- Ost +Agar. carbocation is generated by reaching alkyl halice with silva riterte and then etland attacks ces micheophile to give thee as final product CH₂CH=CH-vez & Agro Chich are tags со, о, о, со си е, о, о, о, , ул Reachirty older stable the carlocation reaction faster the Reaction proceeds by SN 2 mee hanern. so the reactivity order is.

Page No.: Date: Tertiary halides produces a precipitate almost instantly Secondary halides gires slight poccipitate after few seconds. Primary halide takes a longer time Aromatic balide, are unractive because of unfavourable attack of nucleophile from backsile in sN? deaction and ring does not allow formation of carlocation in SN1 seaction. so ractivity older for Ag Noleton Bromo adamantane > 2 bromo-2 metayl poopane > 2 bronco beltane > I bromobeltone bromobenzene, a bromatoline] reacts selowlegt Bromo ad montare in 30 halide that's why. roch fastest
Nal/acetone promotes sn2 reactions so reactivity is fastest for primary halides and slowest for tertiary ones

On the other hand silver nitrate and ethanol promotes sn1 reactions so reactivity is of opposites order tertiary halides reacts fastest and primary halides reacts the slowest.
