Question

Major and Minor For SN2 and SN1 reaction of this:

OH NaOH (aq), EtOH + - Br

Answer 1

I SN Reaction :- Substitution Nucleophilic Unimolecular reaction. The rate of this reaction depends upon the concentration of only are reactant i.e. substante molecule (alkyl halide) The order of reactivity of alkyl ha in case of SNl reaction is as given, allde It meane that 3 alkye hall de reacts faster or rapiary with nucleophile rather 20 of 1 Here, isopropyl bromide (2) is more reactive with nucleophile than n-propye branide (10). Reaction :- Br (SNI) NaOH (9) minor + Eloh 4 / major

Mechanism :- step 1 - Formation of carbocation. for slow yo 20 cascocation steps: attack of Nucleophile 2 - (Major) 20 camocation 10 / primary. cabocation C order of stability and hence above product is major.

an Nucleophilic ② sx² Reaction :- Substitution Nucleoft Bimolecular Reaction. The rate of this reaction depends upon to pon the concentration of both reactants. Frimary alkye halide is more reactive than 20 4 3 alkye halide in case of SN Reaction because it is single step reaction in which attack of Nucleophile and departure of leaving group takes Place simultaneously Here Br je n-propyl bro treated fastly with nucleophile than Br je isopropyl bromide because first one is primary and other 20 Reach - very quick oth Br Mart (109) h ar it py ToH tot Major) slow attack (Minor
