4. Draw the expected major product that results from each of the following Sy2 reactions S Na + NaNO2 + Nang + NaCN f) YO + NaCN TH

Answer 1

solutions : Na* + Because Other Byomine also gives substi Hakon product but SN mechanism If we considers SNL Cyanide will alacs Nom axial side o other bromine (tis at equilonial position) to give above SNZ product S2 + A BB -Na N suzade51A PANIN-NON Abagnar. Here, we know that Bromine is good leaving group so nucleophulle arack 7 thiol sulphut to give SN2 Substitution product. etylphenylsulfide b Here Iodine is bellow the planer paper So, azide ion (N2) will alack from above the plane to give above. Thus its Stefa chemistry will changed. as shown in above! . We know that halorens are more electronegative than carbond. so their f) ch I bond should be partially polarised. To sive SN2 product as above (5N2Xq R T +NANT B1 (S2) stan67 ! Here se carbon not shows SN2 reaction while sp3 carbon is present so gives above product. Because 5-bond Pepe opposes to nucleophiclic Hack of Q2ide (na) ion.so prefereblely I selectively other Bromine is substituted. Nor + NaCN SN21 rean. toreq SJEĆ product. aria
