In each reaction box, place the best reagent and conditions from the list below. 3) 4) 5) 6) 1) 2) CH NaNH2 CHCOO Na, NH3 (1) Br2, hv CHsCH2Br HCEC NaOH H2O, mild HoO BH3THF Br2

Answer 1

Given product is cyclopentane now from the given products select the Br, and react it with cyclopentane in presence of light called as bromination which gives the bromocyclopentane further make it react with NaOH which gives the cyclopentene 1) Br. hv 2) NaOH cyclopentene cyclopentane bromocyclopentane as epoxidation further epoxide was opened by ethylene anion then its reaction with water will give ethynylcyclopentanol When ethynylcyclopentanol reacts with PCC then its functional group alcohol tums into ketone. он 4) HCC 5) H O, mild Ho 3) mCPBA 0 с ЕСН CH 2-cthynylcyclopentanol 6-oxabicyclol3.1.0hexane 6) PCC CH 2-cthynyleyclopentanone
