_3. Which reagent would be the best reagent for the following reaction? (4 pts) ony Br Br HzC- H3C- a) H2N-NH/KOH b) NaBH4 in ethanol c) 1) HS-CH2CH2-SH 2) Hz/Pt d) HCl/Zn/Hg Explain your answer by describing why the other 3 options would NOT work as well.

Answer 1

4₂0 Nit - Nitty, kot, will give the product via Wolff-kishner meahim. But here Kolt used is a strong base other side reaction such as elimination can also Br nou te - BY spell onjugate bare ECB mection So this good. lao to c-04 glue o to c-04 to does not (stable a, ß unsational relone) method is not abita in ethanol comest The desired product. So this is not correct reallet. 1 H3-CH-12-14 2) H et is the best reagent as it requtes. slight acidic condition for the first step ie, process throacetal formation. now finally talet removed this c) Dits- unegui [ a Belectively giving me product as enclusive one Hellen-4g in clemmensen reduction which requires as wart condition ie; not Hel with Zn leg ocoring via radical mechn. so this is not appropriate other side product may ocuri so the correct option ! @ @ 4s-chef-shoulpt
