Question

In the example, why would we use NaN3 instead of CH3CN?

Why choose Na Nz instead of CHE LN? NaN3, CH₃CN Sul/E,

Answer 1

here the nucleophilicity as well as the basic character of N₃^- is greater than the CH₃CN thus N3- give the SN1 and E1 reaction.

7.Br Dok na a > N3 SN, product Here this is the tartiarey bromide, after Br elemination it form tartiary carbocation (3° carbocation) which is more stable Now NaNg is is strong electrolyte split into Nat 13 where l acts as strong nucleophile nucleophile as well as a base. so ona acts as SN' reaction and also E reaction by taking the proton and give two product. Here not basic and to give give the also have reaction on not a strong nucheophile and participate in SN and E For that reason CH₂ CM CH₂ CN is not character to the produit. reaction.
