Reaction #6 Н D CH2CI2 NaN3 E OThe major organic product arises from front face attack by the N3 anion at atom D O The major organic product arises from front face attack by the N3 anion at atom E OThe major organic product arises from back face attack by the N3 anion at atom D The major organic product arises from back face attack by the N3 anion at atom E Question 8 [1.5 pts] What is the configuration of carbon F in the major organic product obtained at the conclusion of the reaction sequence noted in Figure #1? Hint Each one of the three reactions in Figure # 1 is an SN2 reaction Figure #1 CI н NaBr Nal NaCN CeH13 CeH13Br C7H13N acetone, heat acetone, heat acetone, heat (optically active) (optically active) (optically active) F O R O S O None of the above

Answer 1

Nu mon- Here the Nana is groot given in polar aprotic solvent CHOL. 3o, Ny is a good mucleophile and the reaction both Wory is SN2 30, obviously No attack from the Boreksite of the chloroniumion. Now, the attack will occure at the more substituted C-atom an thin e atom (here El cam accommodate st charge better. The major product arisen from back side attack by the N₂ Mion at atom E

Ho del Nabr Geelone (R) NaI acetone, A I @CNH NGON acetone, (R) Here in each case SN2 reaction takes place. In SAZ alwes the incoming nucleophile attack from the back side of the leaving group so, in each reaction inversion of configuration resulten. So, the configuration of the final product in R
